Let's divide 77178707 by 988
We want to divide 77178707 by 988.

Moving on to step 1:
If we divide 7 by 988, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 988

Going ahead to step 2:
988 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 988

Advancing to step 3:
If we divide 771 by 988, we get 0 and a remainder of 771.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 771 leaves us with 771.
Grab the next digit (7) from the dividend, add it to 771, then carry on: 7717 / 988

Advancing to step 4:
7717 divided by 988 is 7 with a remainder of 801.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6916 from 7717 to get 801.
Append the next digit (8) from the dividend to 801 and continue with: 8018 / 988

Going ahead to step 5:
When dividing 8018 by 988, we get 8 with a remainder of 114.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 7904 from 8018 leaves us with 114.
Bring next digit (7) of the dividend behind the 114 and repeat the process: 1147 / 988

Advancing to step 6:
988 goes into 1147 1 times with a remainder of 159.
Use 1 as the next digit of our solution. 
Result so far: 781.0
If we take 988 away from 1147, we end up with 159.
Fetch the next digit (0) from the dividend, attach it to 159 and continue: 1590 / 988

Moving on to step 7:
988 goes into 1590 1 times with a remainder of 602.
Put 1 as the next digit of the answer. 
Result so far: 7811.0
The remainder is 602 after subtracting 988 from 1590.
Include the next digit (7) from the dividend after 602, then repeat: 6027 / 988

Going ahead to step 8:
If we divide 6027 by 988, we get 6 and a remainder of 99.
The number 6 becomes the next digit in our result. 
Result so far: 78116.0
Subtracting 5928 from 6027 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
The number 988 fits into 990 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 78116.1
If we take 988 away from 990, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
988 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 78116.1
Deduct 0 from 20 and we're left with 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:
988 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 78116.1
Subtracting 0 from 200 leaves us 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 78116.1 with a remainder of 0.02.
