Let's divide 31680919 by 155
Our goal is to divide 31680919 by 155.

On to step 1:
3 divided by 155 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 155

On to step 2:
155 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 155

Going ahead to step 3:
155 can be fit into 316 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 310 from 316, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 155

Advancing to step 4:
If we divide 68 by 155, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 68 to get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 155

Going ahead to step 5:
When dividing 680 by 155, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 204.0
If we take 620 away from 680, we end up with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 155

Going ahead to step 6:
155 goes into 609 3 times with a remainder of 144.
Use 3 as the next digit of our solution. 
Result so far: 2043.0
The remainder is 144 after subtracting 465 from 609.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 155

Going ahead to step 7:
155 goes into 1441 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 20439.0
The remainder is 46 after subtracting 1395 from 1441.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 155

Advancing to step 8:
The number 155 fits into 469 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 204393.0
Deduct 465 from 469 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 155 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 204393.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
155 goes into 400 2 times with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 204393.02
Subtracting 310 from 400 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
The number 155 fits into 900 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 204393.025
Deduct 775 from 900 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 155 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 204393.0258
Deduct 1240 from 1250 and we're left 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.

On to step 13:
155 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 204393.0258
The remainder is 100 after subtracting 0 from 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 14:
1000 divided by 155 is 6 with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 204393.025806
Deduct 930 from 1000 and we're left 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 15:
700 divided by 155 is 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 204393.0258064
The remainder is 80 after subtracting 620 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
155 can be fit into 800 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 204393.02580645
Subtract 775 from 800 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 204393.02580645 with a remaining 2.5e-08.
