We're dividing 31800328 by 263 
Our goal is to divide 31800328 by 263.

Moving on to step 1:
If we divide 3 by 263, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 263

Moving on to step 2:
If we divide 31 by 263, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 263

Moving on to step 3:
If we divide 318 by 263, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 263 from 318 and we're left with 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 263

Let's proceed to step 4:
550 divided by 263 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 526 away from 550, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 263

On to step 5:
If we divide 240 by 263, we get 0 and a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 240, we get 240.
Include the next digit (3) from the dividend after 240, then repeat: 2403 / 263

Advancing to step 6:
263 goes into 2403 9 times with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 1209.0
Subtracting 2367 from 2403 leaves us with 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 263

Moving on to step 7:
The number 263 fits into 362 1 times, leaving a remainder of 99.
The next digit of our result is 1. 
Result so far: 12091.0
If we take 263 away from 362, we end up with 99.
Include the next digit (8) from the dividend after 99, then repeat: 998 / 263

Going ahead to step 8:
The number 263 fits into 998 3 times, leaving a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 120913.0
Deduct 789 from 998 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
When dividing 2090 by 263, we get 7 with a remainder of 249.
The next digit of our result is 7. 
Result so far: 120913.7
The remainder is 249 after subtracting 1841 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 10:
263 can be fit into 2490 9 times, resulting in a remainder of 123.
Write down 9 as next digit of the result. 
Result so far: 120913.79
The remainder is 123 after subtracting 2367 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 11:
If we divide 1230 by 263, we get 4 and a remainder of 178.
The number 4 becomes the next digit in our result. 
Result so far: 120913.794
Deduct 1052 from 1230 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 12:
If we divide 1780 by 263, we get 6 and a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 120913.7946
Subtracting 1578 from 1780 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 13:
263 goes into 2020 7 times with a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 120913.79467
If we subtract 1841 from 2020, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 14:
1790 divided by 263 is 6 with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 120913.794676
Subtracting 1578 from 1790 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 15:
263 can be fit into 2120 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 120913.7946768
Deduct 2104 from 2120 and we're left 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.

Going ahead to step 16:
263 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 120913.7946768
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 120913.7946768, with a leftover of 1.6e-07.
