We're dividing 80978263 by 861 
We're looking to find how many times 861 goes into 80978263.

Step 1:
8 divided by 861 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 861

Going ahead to step 2:
861 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 861

Let's proceed to step 3:
861 goes into 809 0 times with a remainder of 809.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 809, we end up with 809.
Include the next digit (7) from the dividend after 809, then repeat: 8097 / 861

On to step 4:
When dividing 8097 by 861, we get 9 with a remainder of 348.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7749 from 8097 and we're left with 348.
Fetch the next digit (8) from the dividend, attach it to 348 and continue: 3488 / 861

Let's proceed to step 5:
861 can be fit into 3488 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we subtract 3444 from 3488, we get 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 861

On to step 6:
If we divide 442 by 861, we get 0 and a remainder of 442.
Use 0 as the next digit of our solution. 
Result so far: 940.0
The remainder is 442 after subtracting 0 from 442.
Grab the next digit (6) from the dividend, add it to 442, then carry on: 4426 / 861

Going ahead to step 7:
If we divide 4426 by 861, we get 5 and a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 9405.0
Deduct 4305 from 4426 and we're left with 121.
Bring next digit (3) of the dividend behind the 121 and repeat the process: 1213 / 861

Let's proceed to step 8:
1213 divided by 861 is 1 with a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 94051.0
The remainder is 352 after subtracting 861 from 1213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 9:
861 can be fit into 3520 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 94051.4
The remainder is 76 after subtracting 3444 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
When dividing 760 by 861, we get 0 with a remainder of 760.
The next digit of our result is 0. 
Result so far: 94051.4
Subtract 0 from 760 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 11:
When dividing 7600 by 861, we get 8 with a remainder of 712.
Write down 8 as next digit of the result. 
Result so far: 94051.408
Deduct 6888 from 7600 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 12:
861 can be fit into 7120 8 times, resulting in a remainder of 232.
Write down 8 as next digit of the result. 
Result so far: 94051.4088
If we subtract 6888 from 7120, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final outcome is 94051.4088, with a leftover of 0.00232.
