Let's divide 86646194 by 684
We're looking to find how many times 684 goes into 86646194.

Step 1:
684 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 684

Going ahead to step 2:
684 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 684

Going ahead to step 3:
When dividing 866 by 684, we get 1 with a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 684 from 866 to get 182.
Include the next digit (4) from the dividend after 182, then repeat: 1824 / 684

On to step 4:
If we divide 1824 by 684, we get 2 and a remainder of 456.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1368 from 1824 to get 456.
Take the next digit (6) from the dividend and append it to 456, then repeat: 4566 / 684

Let's proceed to step 5:
4566 divided by 684 is 6 with a remainder of 462.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 4104 from 4566, we get 462.
Take the next digit (1) from the dividend and append it to 462, then repeat: 4621 / 684

Let's proceed to step 6:
684 goes into 4621 6 times with a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
Subtract 4104 from 4621 to get 517.
Fetch the next digit (9) from the dividend, attach it to 517 and continue: 5179 / 684

Going ahead to step 7:
5179 divided by 684 is 7 with a remainder of 391.
Use 7 as the next digit of our solution. 
Result so far: 12667.0
Deduct 4788 from 5179 and we're left with 391.
Include the next digit (4) from the dividend after 391, then repeat: 3914 / 684

Step 8:
If we divide 3914 by 684, we get 5 and a remainder of 494.
Put 5 as the next digit of the answer. 
Result so far: 126675.0
Subtracting 3420 from 3914 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

On to step 9:
684 goes into 4940 7 times with a remainder of 152.
The number 7 becomes the next digit in our result. 
Result so far: 126675.7
Subtracting 4788 from 4940 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
If we divide 1520 by 684, we get 2 and a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 126675.72
Subtracting 1368 from 1520 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 11:
When dividing 1520 by 684, we get 2 with a remainder of 152.
The next digit of our result is 2. 
Result so far: 126675.722
If we subtract 1368 from 1520, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final outcome is 126675.722, with a leftover of 0.0152.
