We look at the division of 749123 by 31 
We want to figure out the number of times 749123 can be divided by 31.

Advancing to step 1:
31 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 31

Moving on to step 2:
74 divided by 31 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 62 away from 74, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 31

Moving on to step 3:
When dividing 129 by 31, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 124 from 129 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 31

On to step 4:
51 divided by 31 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 241.0
Subtract 31 from 51 to get 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 31

Let's proceed to step 5:
31 goes into 202 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 2416.0
The remainder is 16 after subtracting 186 from 202.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 31

Step 6:
If we divide 163 by 31, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 24165.0
If we subtract 155 from 163, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 24165.2
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
31 can be fit into 180 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 24165.25
Subtract 155 from 180 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.

Going ahead to step 9:
31 can be fit into 250 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 24165.258
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 31, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 24165.258
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 31, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 24165.25806
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 24165.258064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 24165.2580645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
If we divide 50 by 31, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 24165.25806451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 24165.25806451 and a remainder of 1.9e-08.
