78372 divided by 90 
We're looking to find how many times 90 goes into 78372.

Advancing to step 1:
90 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 90

Advancing to step 2:
90 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 90

Let's proceed to step 3:
When dividing 783 by 90, we get 8 with a remainder of 63.
The next digit of our result is 8. 
Result so far: 8.0
If we take 720 away from 783, we end up with 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 90

Going ahead to step 4:
The number 90 fits into 637 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 87.0
If we subtract 630 from 637, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 90

On to step 5:
If we divide 72 by 90, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
The remainder is 72 after subtracting 0 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 6:
The number 90 fits into 720 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 870.8
Subtracting 720 from 720 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 90 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 870.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 870.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 870.8 with a remaining 0.0.
