We look at the division of 87987104 by 780 
We want to figure out the number of times 87987104 can be divided by 780.

Advancing to step 1:
780 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 780

Advancing to step 2:
87 divided by 780 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 780

Step 3:
When dividing 879 by 780, we get 1 with a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 780 from 879, we get 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 780

Step 4:
780 goes into 998 1 times with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 780 from 998, we get 218.
Take the next digit (7) from the dividend and append it to 218, then repeat: 2187 / 780

On to step 5:
780 goes into 2187 2 times with a remainder of 627.
Write down 2 as next digit of the result. 
Result so far: 112.0
Deduct 1560 from 2187 and we're left with 627.
Bring next digit (1) of the dividend behind the 627 and repeat the process: 6271 / 780

Moving on to step 6:
When dividing 6271 by 780, we get 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 1128.0
If we subtract 6240 from 6271, we get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 780

Moving on to step 7:
310 divided by 780 is 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 11280.0
If we subtract 0 from 310, we get 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 780

Moving on to step 8:
3104 divided by 780 is 3 with a remainder of 764.
Record the quotient 3 as the next digit in the result. 
Result so far: 112803.0
If we take 2340 away from 3104, we end up with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 9:
When dividing 7640 by 780, we get 9 with a remainder of 620.
The next digit of our result is 9. 
Result so far: 112803.9
Subtracting 7020 from 7640 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
If we divide 6200 by 780, we get 7 and a remainder of 740.
The next digit of our result is 7. 
Result so far: 112803.97
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 11:
780 goes into 7400 9 times with a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 112803.979
If we take 7020 away from 7400, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 12:
3800 divided by 780 is 4 with a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 112803.9794
If we subtract 3120 from 3800, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 13:
780 can be fit into 6800 8 times, resulting in a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 112803.97948
If we subtract 6240 from 6800, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 14:
5600 divided by 780 is 7 with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 112803.979487
Subtract 5460 from 5600 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
When dividing 1400 by 780, we get 1 with a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 112803.9794871
The remainder is 620 after subtracting 780 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 16:
780 can be fit into 6200 7 times, resulting in a remainder of 740.
Use 7 as the next digit of our solution. 
Result so far: 112803.97948717
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final outcome is 112803.97948717, with a leftover of 7.4e-07.
