We look at the division of 83579037 by 866 
Let's see how many times 866 fits into 83579037.

On to step 1:
When dividing 8 by 866, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 866

Moving on to step 2:
83 divided by 866 is 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 866

On to step 3:
866 can be fit into 835 0 times, resulting in a remainder of 835.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 835, we get 835.
Include the next digit (7) from the dividend after 835, then repeat: 8357 / 866

Let's proceed to step 4:
866 can be fit into 8357 9 times, resulting in a remainder of 563.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 563 after subtracting 7794 from 8357.
Bring next digit (9) of the dividend behind the 563 and repeat the process: 5639 / 866

Going ahead to step 5:
If we divide 5639 by 866, we get 6 and a remainder of 443.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 443 after subtracting 5196 from 5639.
Include the next digit (0) from the dividend after 443, then repeat: 4430 / 866

On to step 6:
The number 866 fits into 4430 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
Subtracting 4330 from 4430 leaves us with 100.
Take the next digit (3) from the dividend and append it to 100, then repeat: 1003 / 866

On to step 7:
866 can be fit into 1003 1 times, resulting in a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 9651.0
If we subtract 866 from 1003, we get 137.
Bring next digit (7) of the dividend behind the 137 and repeat the process: 1377 / 866

Moving on to step 8:
If we divide 1377 by 866, we get 1 and a remainder of 511.
Use 1 as the next digit of our solution. 
Result so far: 96511.0
Deduct 866 from 1377 and we're left with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Let's proceed to step 9:
When dividing 5110 by 866, we get 5 with a remainder of 780.
Write down 5 as next digit of the result. 
Result so far: 96511.5
If we take 4330 away from 5110, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 10:
866 goes into 7800 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 96511.59
Subtract 7794 from 7800 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
The number 866 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 96511.59
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 866 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 96511.59
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 96511.59 with a remaining 0.006.
