We look at the division of 87578385 by 249 
We're looking to find how many times 249 goes into 87578385.

On to step 1:
249 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 249

On to step 2:
The number 249 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 249

Step 3:
When dividing 875 by 249, we get 3 with a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 747 away from 875, we end up with 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 249

Advancing to step 4:
249 goes into 1287 5 times with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 1245 from 1287, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 249

Advancing to step 5:
249 can be fit into 428 1 times, resulting in a remainder of 179.
Record the quotient 1 as the next digit in the result. 
Result so far: 351.0
Subtracting 249 from 428 leaves us with 179.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 249

Moving on to step 6:
When dividing 1793 by 249, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 3517.0
If we take 1743 away from 1793, we end up with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 249

Let's proceed to step 7:
If we divide 508 by 249, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 35172.0
Deduct 498 from 508 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 249

Let's proceed to step 8:
The number 249 fits into 105 0 times, leaving a remainder of 105.
The next digit of our result is 0. 
Result so far: 351720.0
If we take 0 away from 105, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
If we divide 1050 by 249, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 351720.4
If we subtract 996 from 1050, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
If we divide 540 by 249, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 351720.42
The remainder is 42 after subtracting 498 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
420 divided by 249 is 1 with a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 351720.421
If we take 249 away from 420, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 12:
When dividing 1710 by 249, we get 6 with a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 351720.4216
Subtract 1494 from 1710 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 13:
The number 249 fits into 2160 8 times, leaving a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 351720.42168
Subtract 1992 from 2160 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 14:
If we divide 1680 by 249, we get 6 and a remainder of 186.
The next digit of our result is 6. 
Result so far: 351720.421686
Subtract 1494 from 1680 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
If we divide 1860 by 249, we get 7 and a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 351720.4216867
Subtract 1743 from 1860 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 16:
If we divide 1170 by 249, we get 4 and a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 351720.42168674
Subtracting 996 from 1170 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final outcome is 351720.42168674, with a leftover of 1.74e-07.
