We're dividing 90178139 by 249 
We want to figure out the number of times 90178139 can be divided by 249.

Moving on to step 1:
9 divided by 249 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 249

Moving on to step 2:
When dividing 90 by 249, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 249

Let's proceed to step 3:
249 goes into 901 3 times with a remainder of 154.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 747 from 901 to get 154.
Grab the next digit (7) from the dividend, add it to 154, then carry on: 1547 / 249

On to step 4:
The number 249 fits into 1547 6 times, leaving a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 1494 from 1547 and we're left with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 249

Advancing to step 5:
When dividing 538 by 249, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
Deduct 498 from 538 and we're left with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 249

Moving on to step 6:
The number 249 fits into 401 1 times, leaving a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 3621.0
If we subtract 249 from 401, we get 152.
Append the next digit (3) from the dividend to 152 and continue with: 1523 / 249

Advancing to step 7:
If we divide 1523 by 249, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 36216.0
Subtracting 1494 from 1523 leaves us with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 249

Moving on to step 8:
249 goes into 299 1 times with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 362161.0
If we subtract 249 from 299, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 249 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 362161.2
Subtract 498 from 500 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 249 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 362161.2
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.

Moving on to step 11:
249 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 362161.2
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 362161.2 with a remainder of 0.02.
