79380778 ÷ 903 
We're looking to find how many times 903 goes into 79380778.

On to step 1:
If we divide 7 by 903, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 903

On to step 2:
When dividing 79 by 903, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 903

Advancing to step 3:
903 goes into 793 0 times with a remainder of 793.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 793, we get 793.
Fetch the next digit (8) from the dividend, attach it to 793 and continue: 7938 / 903

Let's proceed to step 4:
903 can be fit into 7938 8 times, resulting in a remainder of 714.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7224 from 7938 leaves us with 714.
Grab the next digit (0) from the dividend, add it to 714, then carry on: 7140 / 903

Let's proceed to step 5:
When dividing 7140 by 903, we get 7 with a remainder of 819.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 6321 from 7140 leaves us with 819.
Grab the next digit (7) from the dividend, add it to 819, then carry on: 8197 / 903

On to step 6:
903 can be fit into 8197 9 times, resulting in a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 879.0
If we take 8127 away from 8197, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 903

Step 7:
903 can be fit into 707 0 times, resulting in a remainder of 707.
Put 0 as the next digit of the answer. 
Result so far: 8790.0
Deduct 0 from 707 and we're left with 707.
Bring next digit (8) of the dividend behind the 707 and repeat the process: 7078 / 903

Going ahead to step 8:
The number 903 fits into 7078 7 times, leaving a remainder of 757.
Record the quotient 7 as the next digit in the result. 
Result so far: 87907.0
Subtracting 6321 from 7078 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Advancing to step 9:
The number 903 fits into 7570 8 times, leaving a remainder of 346.
The next digit of our result is 8. 
Result so far: 87907.8
Subtract 7224 from 7570 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 10:
When dividing 3460 by 903, we get 3 with a remainder of 751.
Put 3 as the next digit of the answer. 
Result so far: 87907.83
Subtracting 2709 from 3460 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Going ahead to step 11:
903 can be fit into 7510 8 times, resulting in a remainder of 286.
The next digit of our result is 8. 
Result so far: 87907.838
Subtract 7224 from 7510 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 12:
When dividing 2860 by 903, we get 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 87907.8383
The remainder is 151 after subtracting 2709 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 13:
If we divide 1510 by 903, we get 1 and a remainder of 607.
The number 1 becomes the next digit in our result. 
Result so far: 87907.83831
If we take 903 away from 1510, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 14:
6070 divided by 903 is 6 with a remainder of 652.
The number 6 becomes the next digit in our result. 
Result so far: 87907.838316
If we take 5418 away from 6070, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 15:
If we divide 6520 by 903, we get 7 and a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 87907.8383167
The remainder is 199 after subtracting 6321 from 6520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 16:
903 goes into 1990 2 times with a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 87907.83831672
Deduct 1806 from 1990 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 87907.83831672 with a remainder of 1.84e-07.
