Let's divide 1851317 by 231
We're looking to find how many times 231 goes into 1851317.

Advancing to step 1:
231 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 231

On to step 2:
The number 231 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 231

Moving on to step 3:
185 divided by 231 is 0 with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 185 after subtracting 0 from 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 231

Let's proceed to step 4:
If we divide 1851 by 231, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 3 after subtracting 1848 from 1851.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 231

Going ahead to step 5:
When dividing 33 by 231, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 231

Moving on to step 6:
331 divided by 231 is 1 with a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 801.0
Subtracting 231 from 331 leaves us with 100.
Take the next digit (7) from the dividend and append it to 100, then repeat: 1007 / 231

Advancing to step 7:
231 goes into 1007 4 times with a remainder of 83.
The next digit of our result is 4. 
Result so far: 8014.0
Subtracting 924 from 1007 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 8:
231 goes into 830 3 times with a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 8014.3
If we subtract 693 from 830, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
231 goes into 1370 5 times with a remainder of 215.
The next digit of our result is 5. 
Result so far: 8014.35
If we subtract 1155 from 1370, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 10:
When dividing 2150 by 231, we get 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 8014.359
Deduct 2079 from 2150 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 11:
710 divided by 231 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 8014.3593
The remainder is 17 after subtracting 693 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
170 divided by 231 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 8014.3593
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
When dividing 1700 by 231, we get 7 with a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 8014.359307
Subtracting 1617 from 1700 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
If we divide 830 by 231, we get 3 and a remainder of 137.
Record the quotient 3 as the next digit in the result. 
Result so far: 8014.3593073
Subtract 693 from 830 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 15:
231 can be fit into 1370 5 times, resulting in a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 8014.35930735
Subtract 1155 from 1370 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 8014.35930735 with a remaining 2.15e-07.
