55699836 divided by 403 
Our goal is to divide 55699836 by 403.

Step 1:
5 divided by 403 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 403

Moving on to step 2:
When dividing 55 by 403, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 403

Moving on to step 3:
If we divide 556 by 403, we get 1 and a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 153 after subtracting 403 from 556.
Bring next digit (9) of the dividend behind the 153 and repeat the process: 1539 / 403

On to step 4:
1539 divided by 403 is 3 with a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1209 away from 1539, we end up with 330.
Fetch the next digit (9) from the dividend, attach it to 330 and continue: 3309 / 403

Advancing to step 5:
If we divide 3309 by 403, we get 8 and a remainder of 85.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we subtract 3224 from 3309, we get 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 403

Moving on to step 6:
403 goes into 858 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 1382.0
If we take 806 away from 858, we end up with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 403

Advancing to step 7:
If we divide 523 by 403, we get 1 and a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 13821.0
The remainder is 120 after subtracting 403 from 523.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 403

Moving on to step 8:
403 can be fit into 1206 2 times, resulting in a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 138212.0
Subtracting 806 from 1206 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 9:
403 goes into 4000 9 times with a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 138212.9
Subtracting 3627 from 4000 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 10:
3730 divided by 403 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 138212.99
The remainder is 103 after subtracting 3627 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final outcome is 138212.99, with a leftover of 0.103.
