Let's divide 8639740 by 249
We want to divide 8639740 by 249.

Step 1:
The number 249 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 249

Let's proceed to step 2:
249 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 249

Step 3:
If we divide 863 by 249, we get 3 and a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 747 from 863 leaves us with 116.
Grab the next digit (9) from the dividend, add it to 116, then carry on: 1169 / 249

Let's proceed to step 4:
1169 divided by 249 is 4 with a remainder of 173.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 996 from 1169 to get 173.
Take the next digit (7) from the dividend and append it to 173, then repeat: 1737 / 249

On to step 5:
249 goes into 1737 6 times with a remainder of 243.
Write down 6 as next digit of the result. 
Result so far: 346.0
Subtract 1494 from 1737 to get 243.
Append the next digit (4) from the dividend to 243 and continue with: 2434 / 249

Moving on to step 6:
249 goes into 2434 9 times with a remainder of 193.
The next digit of our result is 9. 
Result so far: 3469.0
Deduct 2241 from 2434 and we're left with 193.
Take the next digit (0) from the dividend and append it to 193, then repeat: 1930 / 249

Moving on to step 7:
When dividing 1930 by 249, we get 7 with a remainder of 187.
The number 7 becomes the next digit in our result. 
Result so far: 34697.0
Subtract 1743 from 1930 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 8:
When dividing 1870 by 249, we get 7 with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 34697.7
If we subtract 1743 from 1870, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
249 goes into 1270 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 34697.75
Subtracting 1245 from 1270 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
249 goes into 250 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 34697.751
If we take 249 away from 250, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
When dividing 10 by 249, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 34697.751
Subtracting 0 from 10 leaves us 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 249 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 34697.751
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.

Our division results in 34697.751 with a remaining 0.0001.
