We look at the division of 51904988 by 403 
Our goal is to divide 51904988 by 403.

On to step 1:
When dividing 5 by 403, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 403

Step 2:
51 divided by 403 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 403

Let's proceed to step 3:
When dividing 519 by 403, we get 1 with a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
If we take 403 away from 519, we end up with 116.
Take the next digit (0) from the dividend and append it to 116, then repeat: 1160 / 403

Let's proceed to step 4:
When dividing 1160 by 403, we get 2 with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 806 away from 1160, we end up with 354.
Fetch the next digit (4) from the dividend, attach it to 354 and continue: 3544 / 403

On to step 5:
The number 403 fits into 3544 8 times, leaving a remainder of 320.
The next digit of our result is 8. 
Result so far: 128.0
Deduct 3224 from 3544 and we're left with 320.
Include the next digit (9) from the dividend after 320, then repeat: 3209 / 403

Advancing to step 6:
When dividing 3209 by 403, we get 7 with a remainder of 388.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
Subtract 2821 from 3209 to get 388.
Append the next digit (8) from the dividend to 388 and continue with: 3888 / 403

Advancing to step 7:
If we divide 3888 by 403, we get 9 and a remainder of 261.
The number 9 becomes the next digit in our result. 
Result so far: 12879.0
The remainder is 261 after subtracting 3627 from 3888.
Grab the next digit (8) from the dividend, add it to 261, then carry on: 2618 / 403

Let's proceed to step 8:
403 can be fit into 2618 6 times, resulting in a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 128796.0
The remainder is 200 after subtracting 2418 from 2618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
2000 divided by 403 is 4 with a remainder of 388.
Put 4 as the next digit of the answer. 
Result so far: 128796.4
Subtracting 1612 from 2000 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 10:
403 can be fit into 3880 9 times, resulting in a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 128796.49
The remainder is 253 after subtracting 3627 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 11:
403 goes into 2530 6 times with a remainder of 112.
The next digit of our result is 6. 
Result so far: 128796.496
If we subtract 2418 from 2530, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
403 can be fit into 1120 2 times, resulting in a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 128796.4962
If we take 806 away from 1120, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 13:
The number 403 fits into 3140 7 times, leaving a remainder of 319.
The number 7 becomes the next digit in our result. 
Result so far: 128796.49627
Subtracting 2821 from 3140 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 14:
3190 divided by 403 is 7 with a remainder of 369.
The number 7 becomes the next digit in our result. 
Result so far: 128796.496277
Subtract 2821 from 3190 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The final result is 128796.496277 with a remainder of 3.69e-05.
