Let's divide 76243499 by 31
We're looking to find how many times 31 goes into 76243499.

On to step 1:
The number 31 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 31

Going ahead to step 2:
31 can be fit into 76 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 14 after subtracting 62 from 76.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 31

On to step 3:
If we divide 142 by 31, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 18 after subtracting 124 from 142.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 31

Advancing to step 4:
The number 31 fits into 184 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
If we take 155 away from 184, we end up with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 31

Advancing to step 5:
The number 31 fits into 293 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 2459.0
Subtract 279 from 293 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 31

Advancing to step 6:
If we divide 144 by 31, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 24594.0
Subtract 124 from 144 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 31

On to step 7:
When dividing 209 by 31, we get 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 245946.0
If we take 186 away from 209, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 31

Step 8:
31 can be fit into 239 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 2459467.0
Subtracting 217 from 239 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
31 goes into 220 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2459467.7
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2459467.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
31 goes into 300 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 2459467.709
Subtracting 279 from 300 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
If we divide 210 by 31, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2459467.7096
Deduct 186 from 210 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2459467.70967
Deduct 217 from 240 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 2459467.709677
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 2459467.709677, with a leftover of 1.3e-06.
