We look at the division of 702139 by 87 
Let's see how many times 87 fits into 702139.

Going ahead to step 1:
When dividing 7 by 87, we get 0 with 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.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 87

Advancing to step 2:
When dividing 70 by 87, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 87

Advancing to step 3:
87 goes into 702 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 696 away from 702, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 87

On to step 4:
87 can be fit into 61 0 times, resulting in a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 61, we end up with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 87

Going ahead to step 5:
When dividing 613 by 87, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 807.0
Subtract 609 from 613 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 87

On to step 6:
If we divide 49 by 87, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 8070.0
Subtract 0 from 49 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
490 divided by 87 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 8070.5
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
The number 87 fits into 550 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 8070.56
If we subtract 522 from 550, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 87, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 8070.563
The remainder is 19 after subtracting 261 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
The number 87 fits into 190 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 8070.5632
If we subtract 174 from 190, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 87, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 8070.56321
The remainder is 73 after subtracting 87 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 12:
When dividing 730 by 87, we get 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 8070.563218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
The number 87 fits into 340 3 times, leaving a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 8070.5632183
Subtract 261 from 340 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
The number 87 fits into 790 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 8070.56321839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 8070.56321839 with a balance of 7e-09.
