79331059 ÷ 866 
We want to divide 79331059 by 866.

Advancing to step 1:
866 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 866

Going ahead to step 2:
If we divide 79 by 866, we get 0 and a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 866

Step 3:
When dividing 793 by 866, we get 0 with a remainder of 793.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 793, we get 793.
Append the next digit (3) from the dividend to 793 and continue with: 7933 / 866

Let's proceed to step 4:
866 can be fit into 7933 9 times, resulting in a remainder of 139.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7794 from 7933 to get 139.
Include the next digit (1) from the dividend after 139, then repeat: 1391 / 866

Step 5:
866 goes into 1391 1 times with a remainder of 525.
The next digit of our result is 1. 
Result so far: 91.0
If we take 866 away from 1391, we end up with 525.
Fetch the next digit (0) from the dividend, attach it to 525 and continue: 5250 / 866

Advancing to step 6:
If we divide 5250 by 866, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 916.0
Deduct 5196 from 5250 and we're left with 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 866

Going ahead to step 7:
If we divide 545 by 866, we get 0 and a remainder of 545.
Use 0 as the next digit of our solution. 
Result so far: 9160.0
The remainder is 545 after subtracting 0 from 545.
Grab the next digit (9) from the dividend, add it to 545, then carry on: 5459 / 866

Step 8:
The number 866 fits into 5459 6 times, leaving a remainder of 263.
Use 6 as the next digit of our solution. 
Result so far: 91606.0
If we take 5196 away from 5459, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
866 goes into 2630 3 times with a remainder of 32.
The next digit of our result is 3. 
Result so far: 91606.3
Deduct 2598 from 2630 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 866 fits into 320 0 times, leaving a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 91606.3
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
866 can be fit into 3200 3 times, resulting in a remainder of 602.
Use 3 as the next digit of our solution. 
Result so far: 91606.303
Subtracting 2598 from 3200 leaves us with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 12:
When dividing 6020 by 866, we get 6 with a remainder of 824.
The number 6 becomes the next digit in our result. 
Result so far: 91606.3036
Subtracting 5196 from 6020 leaves us with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Step 13:
866 can be fit into 8240 9 times, resulting in a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 91606.30369
Subtract 7794 from 8240 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 14:
If we divide 4460 by 866, we get 5 and a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 91606.303695
Deduct 4330 from 4460 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 15:
If we divide 1300 by 866, we get 1 and a remainder of 434.
The number 1 becomes the next digit in our result. 
Result so far: 91606.3036951
The remainder is 434 after subtracting 866 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 16:
866 can be fit into 4340 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 91606.30369515
The remainder is 10 after subtracting 4330 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 91606.30369515 with a remaining 1e-08.
