We look at the division of 31001220 by 230 
Our goal is to divide 31001220 by 230.

On to step 1:
The number 230 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 230

Moving on to step 2:
If we divide 31 by 230, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 230

Let's proceed to step 3:
The number 230 fits into 310 1 times, leaving a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 230 from 310 and we're left with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 230

Let's proceed to step 4:
230 can be fit into 800 3 times, resulting in a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 690 away from 800, we end up with 110.
Include the next digit (1) from the dividend after 110, then repeat: 1101 / 230

On to step 5:
230 goes into 1101 4 times with a remainder of 181.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 181 after subtracting 920 from 1101.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 230

On to step 6:
When dividing 1812 by 230, we get 7 with a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 1347.0
If we subtract 1610 from 1812, we get 202.
Bring next digit (2) of the dividend behind the 202 and repeat the process: 2022 / 230

Step 7:
230 goes into 2022 8 times with a remainder of 182.
The number 8 becomes the next digit in our result. 
Result so far: 13478.0
Subtract 1840 from 2022 to get 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 230

On to step 8:
When dividing 1820 by 230, we get 7 with a remainder of 210.
Use 7 as the next digit of our solution. 
Result so far: 134787.0
Subtracting 1610 from 1820 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
2100 divided by 230 is 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 134787.9
The remainder is 30 after subtracting 2070 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
230 goes into 300 1 times with a remainder of 70.
The next digit of our result is 1. 
Result so far: 134787.91
Subtracting 230 from 300 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
230 can be fit into 700 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 134787.913
If we take 690 away from 700, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
The number 230 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 134787.913
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
When dividing 1000 by 230, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 134787.91304
If we take 920 away from 1000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
The number 230 fits into 800 3 times, leaving a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 134787.913043
If we take 690 away from 800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
230 goes into 1100 4 times with a remainder of 180.
The next digit of our result is 4. 
Result so far: 134787.9130434
If we take 920 away from 1100, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
230 goes into 1800 7 times with a remainder of 190.
The number 7 becomes the next digit in our result. 
Result so far: 134787.91304347
Subtracting 1610 from 1800 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 134787.91304347 with a remaining 1.9e-07.
