Let's divide 987451 by 51
Our goal is to divide 987451 by 51.

Advancing to step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 51

On to step 2:
51 goes into 98 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 98, we end up with 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 51

Advancing to step 3:
When dividing 477 by 51, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 459 from 477 and we're left with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 51

Moving on to step 4:
51 goes into 184 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 193.0
If we take 153 away from 184, we end up with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 51

Advancing to step 5:
51 can be fit into 315 6 times, resulting in a remainder of 9.
The next digit of our result is 6. 
Result so far: 1936.0
Deduct 306 from 315 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 51

Advancing to step 6:
When dividing 91 by 51, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 19361.0
If we take 51 away from 91, we end up 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.

Going ahead to step 7:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 19361.7
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
When dividing 430 by 51, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 19361.78
Deduct 408 from 430 and we're left 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.

Step 9:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 19361.784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
51 goes into 160 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 19361.7843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
When dividing 70 by 51, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 19361.78431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
If we divide 190 by 51, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 19361.784313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
370 divided by 51 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 19361.7843137
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.

Moving on to step 14:
When dividing 130 by 51, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 19361.78431372
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.

The quotient of the division is 19361.78431372, and the remainder is 2.8e-08.
