We look at the division of 70523102 by 861 
We want to figure out the number of times 70523102 can be divided by 861.

Going ahead to step 1:
If we divide 7 by 861, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 861

Moving on to step 2:
When dividing 70 by 861, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 861

Going ahead to step 3:
861 can be fit into 705 0 times, resulting in a remainder of 705.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 705, we get 705.
Take the next digit (2) from the dividend and append it to 705, then repeat: 7052 / 861

On to step 4:
7052 divided by 861 is 8 with a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6888 away from 7052, we end up with 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 861

On to step 5:
If we divide 1643 by 861, we get 1 and a remainder of 782.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 861 from 1643, we get 782.
Take the next digit (1) from the dividend and append it to 782, then repeat: 7821 / 861

Let's proceed to step 6:
When dividing 7821 by 861, we get 9 with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 819.0
Subtract 7749 from 7821 to get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 861

On to step 7:
When dividing 720 by 861, we get 0 with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 8190.0
Deduct 0 from 720 and we're left with 720.
Append the next digit (2) from the dividend to 720 and continue with: 7202 / 861

On to step 8:
When dividing 7202 by 861, we get 8 with a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 81908.0
If we take 6888 away from 7202, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
861 goes into 3140 3 times with a remainder of 557.
Record the quotient 3 as the next digit in the result. 
Result so far: 81908.3
Deduct 2583 from 3140 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Advancing to step 10:
If we divide 5570 by 861, we get 6 and a remainder of 404.
Put 6 as the next digit of the answer. 
Result so far: 81908.36
If we take 5166 away from 5570, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
When dividing 4040 by 861, we get 4 with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 81908.364
The remainder is 596 after subtracting 3444 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 12:
861 can be fit into 5960 6 times, resulting in a remainder of 794.
Record the quotient 6 as the next digit in the result. 
Result so far: 81908.3646
If we take 5166 away from 5960, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Advancing to step 13:
When dividing 7940 by 861, we get 9 with a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 81908.36469
If we take 7749 away from 7940, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 14:
861 can be fit into 1910 2 times, resulting in a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 81908.364692
If we take 1722 away from 1910, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 15:
When dividing 1880 by 861, we get 2 with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 81908.3646922
The remainder is 158 after subtracting 1722 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final result is 81908.3646922 with a remainder of 1.58e-06.
