76902039 divided by 870 
We want to figure out the number of times 76902039 can be divided by 870.

Advancing to step 1:
If we divide 7 by 870, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 870

Step 2:
The number 870 fits into 76 0 times, leaving a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 870

Moving on to step 3:
769 divided by 870 is 0 with a remainder of 769.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 769 and we're left with 769.
Include the next digit (0) from the dividend after 769, then repeat: 7690 / 870

On to step 4:
870 can be fit into 7690 8 times, resulting in a remainder of 730.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6960 from 7690 and we're left with 730.
Append the next digit (2) from the dividend to 730 and continue with: 7302 / 870

Moving on to step 5:
870 goes into 7302 8 times with a remainder of 342.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 342 after subtracting 6960 from 7302.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 870

Step 6:
When dividing 3420 by 870, we get 3 with a remainder of 810.
Put 3 as the next digit of the answer. 
Result so far: 883.0
Subtract 2610 from 3420 to get 810.
Bring next digit (3) of the dividend behind the 810 and repeat the process: 8103 / 870

On to step 7:
The number 870 fits into 8103 9 times, leaving a remainder of 273.
Use 9 as the next digit of our solution. 
Result so far: 8839.0
If we subtract 7830 from 8103, we get 273.
Append the next digit (9) from the dividend to 273 and continue with: 2739 / 870

Step 8:
870 can be fit into 2739 3 times, resulting in a remainder of 129.
The next digit of our result is 3. 
Result so far: 88393.0
Subtracting 2610 from 2739 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 9:
1290 divided by 870 is 1 with a remainder of 420.
The next digit of our result is 1. 
Result so far: 88393.1
The remainder is 420 after subtracting 870 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
870 goes into 4200 4 times with a remainder of 720.
Put 4 as the next digit of the answer. 
Result so far: 88393.14
If we take 3480 away from 4200, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 11:
When dividing 7200 by 870, we get 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 88393.148
Subtracting 6960 from 7200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
870 can be fit into 2400 2 times, resulting in a remainder of 660.
Write down 2 as next digit of the result. 
Result so far: 88393.1482
If we take 1740 away from 2400, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 13:
When dividing 6600 by 870, we get 7 with a remainder of 510.
Write down 7 as next digit of the result. 
Result so far: 88393.14827
Deduct 6090 from 6600 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 14:
870 goes into 5100 5 times with a remainder of 750.
Put 5 as the next digit of the answer. 
Result so far: 88393.148275
If we subtract 4350 from 5100, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 15:
When dividing 7500 by 870, we get 8 with a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 88393.1482758
Subtract 6960 from 7500 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 16:
5400 divided by 870 is 6 with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 88393.14827586
If we subtract 5220 from 5400, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 88393.14827586 with a balance of 1.8e-07.
