We're dividing 21815479 by 617 
We want to figure out the number of times 21815479 can be divided by 617.

Moving on to step 1:
If we divide 2 by 617, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 617

Moving on to step 2:
617 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 617

Going ahead to step 3:
617 can be fit into 218 0 times, resulting in a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Append the next digit (1) from the dividend to 218 and continue with: 2181 / 617

On to step 4:
The number 617 fits into 2181 3 times, leaving a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1851 from 2181, we get 330.
Take the next digit (5) from the dividend and append it to 330, then repeat: 3305 / 617

Let's proceed to step 5:
When dividing 3305 by 617, we get 5 with a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 220 after subtracting 3085 from 3305.
Bring next digit (4) of the dividend behind the 220 and repeat the process: 2204 / 617

Going ahead to step 6:
617 can be fit into 2204 3 times, resulting in a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
If we take 1851 away from 2204, we end up with 353.
Include the next digit (7) from the dividend after 353, then repeat: 3537 / 617

Going ahead to step 7:
3537 divided by 617 is 5 with a remainder of 452.
Put 5 as the next digit of the answer. 
Result so far: 3535.0
Deduct 3085 from 3537 and we're left with 452.
Include the next digit (9) from the dividend after 452, then repeat: 4529 / 617

Moving on to step 8:
617 can be fit into 4529 7 times, resulting in a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 35357.0
If we subtract 4319 from 4529, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
When dividing 2100 by 617, we get 3 with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 35357.3
Subtract 1851 from 2100 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 10:
When dividing 2490 by 617, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 35357.34
If we take 2468 away from 2490, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
If we divide 220 by 617, we get 0 and a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 35357.34
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
When dividing 2200 by 617, we get 3 with a remainder of 349.
Record the quotient 3 as the next digit in the result. 
Result so far: 35357.3403
The remainder is 349 after subtracting 1851 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 13:
If we divide 3490 by 617, we get 5 and a remainder of 405.
The next digit of our result is 5. 
Result so far: 35357.34035
The remainder is 405 after subtracting 3085 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 14:
617 can be fit into 4050 6 times, resulting in a remainder of 348.
The next digit of our result is 6. 
Result so far: 35357.340356
The remainder is 348 after subtracting 3702 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 15:
If we divide 3480 by 617, we get 5 and a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 35357.3403565
If we take 3085 away from 3480, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 16:
617 can be fit into 3950 6 times, resulting in a remainder of 248.
The next digit of our result is 6. 
Result so far: 35357.34035656
Deduct 3702 from 3950 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 35357.34035656 with a balance of 2.48e-07.
