We're dividing 55371505 by 403 
Our goal is to divide 55371505 by 403.

Going ahead 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
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 403

Step 2:
The number 403 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 403

Let's proceed to step 3:
When dividing 553 by 403, we get 1 with a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 403 from 553, we get 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 403

Advancing to step 4:
1507 divided by 403 is 3 with a remainder of 298.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1209 from 1507 leaves us with 298.
Bring next digit (1) of the dividend behind the 298 and repeat the process: 2981 / 403

On to step 5:
When dividing 2981 by 403, we get 7 with a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 2821 from 2981 to get 160.
Grab the next digit (5) from the dividend, add it to 160, then carry on: 1605 / 403

Step 6:
1605 divided by 403 is 3 with a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 1373.0
If we take 1209 away from 1605, we end up with 396.
Include the next digit (0) from the dividend after 396, then repeat: 3960 / 403

Let's proceed to step 7:
3960 divided by 403 is 9 with a remainder of 333.
Use 9 as the next digit of our solution. 
Result so far: 13739.0
If we take 3627 away from 3960, we end up with 333.
Grab the next digit (5) from the dividend, add it to 333, then carry on: 3335 / 403

Going ahead to step 8:
403 can be fit into 3335 8 times, resulting in a remainder of 111.
Write down 8 as next digit of the result. 
Result so far: 137398.0
Subtracting 3224 from 3335 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
1110 divided by 403 is 2 with a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 137398.2
If we subtract 806 from 1110, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 10:
3040 divided by 403 is 7 with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 137398.27
Subtracting 2821 from 3040 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 11:
When dividing 2190 by 403, we get 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 137398.275
Subtracting 2015 from 2190 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 12:
If we divide 1750 by 403, we get 4 and a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 137398.2754
If we take 1612 away from 1750, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 13:
If we divide 1380 by 403, we get 3 and a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 137398.27543
Subtracting 1209 from 1380 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 14:
The number 403 fits into 1710 4 times, leaving a remainder of 98.
The next digit of our result is 4. 
Result so far: 137398.275434
The remainder is 98 after subtracting 1612 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 15:
When dividing 980 by 403, we get 2 with a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 137398.2754342
The remainder is 174 after subtracting 806 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 16:
When dividing 1740 by 403, we get 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 137398.27543424
Deduct 1612 from 1740 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Our division results in 137398.27543424 with a remaining 1.28e-07.
