Let's divide 479215 by 51
We want to figure out the number of times 479215 can be divided by 51.

Step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 51

Going ahead to step 2:
The number 51 fits into 47 0 times, leaving a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 51

Advancing to step 3:
479 divided by 51 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 20 after subtracting 459 from 479.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 51

Going ahead to step 4:
51 goes into 202 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 153 from 202 to get 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 51

Let's proceed to step 5:
51 goes into 491 9 times with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 939.0
If we subtract 459 from 491, we get 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 51

On to step 6:
When dividing 325 by 51, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 9396.0
Deduct 306 from 325 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 9396.3
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 9396.37
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
51 goes into 130 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9396.372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 51, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9396.3725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
If we divide 250 by 51, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 9396.37254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
If we divide 460 by 51, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9396.372549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
10 divided by 51 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 9396.372549
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 51, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 9396.37254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 9396.37254901, with a leftover of 4.9e-08.
