31239804 ÷ 311 
We want to divide 31239804 by 311.

Advancing to step 1:
311 goes into 3 0 times with 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.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 311

Going ahead to step 2:
31 divided by 311 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 311

Advancing to step 3:
311 goes into 312 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 311 from 312.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 311

Let's proceed to step 4:
311 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 13, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 311

Let's proceed to step 5:
When dividing 139 by 311, we get 0 with a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 139, we end up with 139.
Append the next digit (8) from the dividend to 139 and continue with: 1398 / 311

Advancing to step 6:
1398 divided by 311 is 4 with a remainder of 154.
Write down 4 as next digit of the result. 
Result so far: 1004.0
Subtract 1244 from 1398 to get 154.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 311

Going ahead to step 7:
The number 311 fits into 1540 4 times, leaving a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 10044.0
Subtracting 1244 from 1540 leaves us with 296.
Include the next digit (4) from the dividend after 296, then repeat: 2964 / 311

Going ahead to step 8:
311 can be fit into 2964 9 times, resulting in a remainder of 165.
Use 9 as the next digit of our solution. 
Result so far: 100449.0
Deduct 2799 from 2964 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 9:
The number 311 fits into 1650 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 100449.5
If we take 1555 away from 1650, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 10:
311 goes into 950 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 100449.53
Deduct 933 from 950 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
When dividing 170 by 311, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 100449.53
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
311 can be fit into 1700 5 times, resulting in a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 100449.5305
If we take 1555 away from 1700, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 13:
311 goes into 1450 4 times with a remainder of 206.
Record the quotient 4 as the next digit in the result. 
Result so far: 100449.53054
The remainder is 206 after subtracting 1244 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 14:
2060 divided by 311 is 6 with a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 100449.530546
Subtracting 1866 from 2060 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 15:
The number 311 fits into 1940 6 times, leaving a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 100449.5305466
Deduct 1866 from 1940 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 100449.5305466 with a remaining 7.4e-07.
