78979922 divided by 987 
We want to figure out the number of times 78979922 can be divided by 987.

On to step 1:
987 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 987

Step 2:
When dividing 78 by 987, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 987

Going ahead to step 3:
789 divided by 987 is 0 with a remainder of 789.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 789 leaves us with 789.
Fetch the next digit (7) from the dividend, attach it to 789 and continue: 7897 / 987

Step 4:
987 goes into 7897 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 7896 from 7897 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 987

On to step 5:
If we divide 19 by 987, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 19, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 987

Moving on to step 6:
199 divided by 987 is 0 with a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 800.0
The remainder is 199 after subtracting 0 from 199.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 987

Step 7:
If we divide 1992 by 987, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 8002.0
If we subtract 1974 from 1992, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 987

On to step 8:
The number 987 fits into 182 0 times, leaving a remainder of 182.
The next digit of our result is 0. 
Result so far: 80020.0
If we subtract 0 from 182, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 9:
The number 987 fits into 1820 1 times, leaving a remainder of 833.
Use 1 as the next digit of our solution. 
Result so far: 80020.1
Subtracting 987 from 1820 leaves us with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Step 10:
If we divide 8330 by 987, we get 8 and a remainder of 434.
Record the quotient 8 as the next digit in the result. 
Result so far: 80020.18
Deduct 7896 from 8330 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 11:
If we divide 4340 by 987, we get 4 and a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 80020.184
Deduct 3948 from 4340 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
The number 987 fits into 3920 3 times, leaving a remainder of 959.
The next digit of our result is 3. 
Result so far: 80020.1843
The remainder is 959 after subtracting 2961 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9590, and continue the process.

Step 13:
987 goes into 9590 9 times with a remainder of 707.
Write down 9 as next digit of the result. 
Result so far: 80020.18439
Subtract 8883 from 9590 to get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

On to step 14:
When dividing 7070 by 987, we get 7 with a remainder of 161.
Write down 7 as next digit of the result. 
Result so far: 80020.184397
Subtracting 6909 from 7070 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 15:
The number 987 fits into 1610 1 times, leaving a remainder of 623.
Record the quotient 1 as the next digit in the result. 
Result so far: 80020.1843971
If we take 987 away from 1610, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 16:
6230 divided by 987 is 6 with a remainder of 308.
The next digit of our result is 6. 
Result so far: 80020.18439716
Subtract 5922 from 6230 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 80020.18439716, and the remainder is 3.08e-07.
