We're dividing 21559117 by 85 
We're looking to find how many times 85 goes into 21559117.

On to step 1:
85 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 85

Moving on to step 2:
21 divided by 85 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 85

Let's proceed to step 3:
The number 85 fits into 215 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 170 from 215 leaves us with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 85

On to step 4:
The number 85 fits into 455 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 425 from 455 leaves us with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 85

On to step 5:
309 divided by 85 is 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 253.0
Subtract 255 from 309 to get 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 85

Going ahead to step 6:
85 can be fit into 541 6 times, resulting in a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 2536.0
Subtracting 510 from 541 leaves us with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 85

Advancing to step 7:
When dividing 311 by 85, we get 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 25363.0
Subtract 255 from 311 to get 56.
Append the next digit (7) from the dividend to 56 and continue with: 567 / 85

Moving on to step 8:
85 can be fit into 567 6 times, resulting in a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 253636.0
If we take 510 away from 567, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
The number 85 fits into 570 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 253636.6
Subtracting 510 from 570 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
85 goes into 600 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 253636.67
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
85 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 253636.67
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 253636.6705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 253636.67058
Deduct 680 from 750 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
700 divided by 85 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 253636.670588
Subtract 680 from 700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 253636.670588 with a remainder of 2e-06.
