We're dividing 77937642 by 979 
Our goal is to divide 77937642 by 979.

Going ahead to step 1:
When dividing 7 by 979, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 979

Advancing to step 2:
The number 979 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 979

Going ahead to step 3:
The number 979 fits into 779 0 times, leaving a remainder of 779.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 779 after subtracting 0 from 779.
Append the next digit (3) from the dividend to 779 and continue with: 7793 / 979

Let's proceed to step 4:
The number 979 fits into 7793 7 times, leaving a remainder of 940.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6853 from 7793, we get 940.
Grab the next digit (7) from the dividend, add it to 940, then carry on: 9407 / 979

Advancing to step 5:
If we divide 9407 by 979, we get 9 and a remainder of 596.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 596 after subtracting 8811 from 9407.
Include the next digit (6) from the dividend after 596, then repeat: 5966 / 979

Going ahead to step 6:
979 can be fit into 5966 6 times, resulting in a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 796.0
Deduct 5874 from 5966 and we're left with 92.
Take the next digit (4) from the dividend and append it to 92, then repeat: 924 / 979

Advancing to step 7:
The number 979 fits into 924 0 times, leaving a remainder of 924.
Write down 0 as next digit of the result. 
Result so far: 7960.0
The remainder is 924 after subtracting 0 from 924.
Fetch the next digit (2) from the dividend, attach it to 924 and continue: 9242 / 979

Advancing to step 8:
The number 979 fits into 9242 9 times, leaving a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 79609.0
If we take 8811 away from 9242, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 9:
When dividing 4310 by 979, we get 4 with a remainder of 394.
The next digit of our result is 4. 
Result so far: 79609.4
The remainder is 394 after subtracting 3916 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
The number 979 fits into 3940 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 79609.44
If we subtract 3916 from 3940, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 79609.44 and a remainder of 0.024.
