Let's divide 452869 by 51
We're looking to find how many times 51 goes into 452869.

On to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 51

Advancing to step 2:
The number 51 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 51

Advancing to step 3:
If we divide 452 by 51, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 408 from 452, we get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 51

Moving on to step 4:
The number 51 fits into 448 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we take 408 away from 448, we end up with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 51

Going ahead to step 5:
The number 51 fits into 406 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 887.0
If we subtract 357 from 406, we get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 51

Moving on to step 6:
If we divide 499 by 51, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 8879.0
Deduct 459 from 499 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 8879.7
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
51 goes into 430 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8879.78
The remainder is 22 after subtracting 408 from 430.
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 9:
If we divide 220 by 51, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 8879.784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 51 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 8879.7843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
51 goes into 70 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 8879.78431
Deduct 51 from 70 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.

Going ahead to step 12:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 8879.784313
Deduct 153 from 190 and we're left with 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 13:
370 divided by 51 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8879.7843137
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 8879.78431372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 8879.78431372 and a remainder of 2.8e-08.
