Let's divide 86669611 by 847
We want to divide 86669611 by 847.

Moving on to step 1:
8 divided by 847 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 847

Let's proceed to step 2:
86 divided by 847 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 847

Going ahead to step 3:
When dividing 866 by 847, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 847 from 866, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 847

Advancing to step 4:
If we divide 196 by 847, we get 0 and a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 196 leaves us with 196.
Fetch the next digit (9) from the dividend, attach it to 196 and continue: 1969 / 847

On to step 5:
The number 847 fits into 1969 2 times, leaving a remainder of 275.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 275 after subtracting 1694 from 1969.
Take the next digit (6) from the dividend and append it to 275, then repeat: 2756 / 847

On to step 6:
2756 divided by 847 is 3 with a remainder of 215.
Record the quotient 3 as the next digit in the result. 
Result so far: 1023.0
Deduct 2541 from 2756 and we're left with 215.
Fetch the next digit (1) from the dividend, attach it to 215 and continue: 2151 / 847

Moving on to step 7:
847 can be fit into 2151 2 times, resulting in a remainder of 457.
Put 2 as the next digit of the answer. 
Result so far: 10232.0
Deduct 1694 from 2151 and we're left with 457.
Grab the next digit (1) from the dividend, add it to 457, then carry on: 4571 / 847

Let's proceed to step 8:
847 can be fit into 4571 5 times, resulting in a remainder of 336.
Record the quotient 5 as the next digit in the result. 
Result so far: 102325.0
If we take 4235 away from 4571, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
When dividing 3360 by 847, we get 3 with a remainder of 819.
The number 3 becomes the next digit in our result. 
Result so far: 102325.3
Subtract 2541 from 3360 to get 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Going ahead to step 10:
847 goes into 8190 9 times with a remainder of 567.
Put 9 as the next digit of the answer. 
Result so far: 102325.39
If we subtract 7623 from 8190, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 11:
5670 divided by 847 is 6 with a remainder of 588.
The next digit of our result is 6. 
Result so far: 102325.396
Deduct 5082 from 5670 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 12:
If we divide 5880 by 847, we get 6 and a remainder of 798.
Record the quotient 6 as the next digit in the result. 
Result so far: 102325.3966
If we take 5082 away from 5880, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

The final result is 102325.3966 with a remainder of 0.00798.
