86514506 ÷ 684 
Our goal is to divide 86514506 by 684.

On to step 1:
If we divide 8 by 684, we get 0 and 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.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 684

Let's proceed to step 2:
The number 684 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 684

Let's proceed to step 3:
The number 684 fits into 865 1 times, leaving a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 684 from 865, we get 181.
Include the next digit (1) from the dividend after 181, then repeat: 1811 / 684

On to step 4:
If we divide 1811 by 684, we get 2 and a remainder of 443.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1368 from 1811 and we're left with 443.
Fetch the next digit (4) from the dividend, attach it to 443 and continue: 4434 / 684

Going ahead to step 5:
When dividing 4434 by 684, we get 6 with a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 4104 away from 4434, we end up with 330.
Grab the next digit (5) from the dividend, add it to 330, then carry on: 3305 / 684

Moving on to step 6:
When dividing 3305 by 684, we get 4 with a remainder of 569.
Record the quotient 4 as the next digit in the result. 
Result so far: 1264.0
Subtract 2736 from 3305 to get 569.
Append the next digit (0) from the dividend to 569 and continue with: 5690 / 684

Step 7:
The number 684 fits into 5690 8 times, leaving a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 12648.0
Subtract 5472 from 5690 to get 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 684

Let's proceed to step 8:
The number 684 fits into 2186 3 times, leaving a remainder of 134.
The next digit of our result is 3. 
Result so far: 126483.0
Deduct 2052 from 2186 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
When dividing 1340 by 684, we get 1 with a remainder of 656.
Use 1 as the next digit of our solution. 
Result so far: 126483.1
If we subtract 684 from 1340, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 10:
684 can be fit into 6560 9 times, resulting in a remainder of 404.
Put 9 as the next digit of the answer. 
Result so far: 126483.19
If we subtract 6156 from 6560, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
4040 divided by 684 is 5 with a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 126483.195
If we subtract 3420 from 4040, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 12:
The number 684 fits into 6200 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 126483.1959
Subtract 6156 from 6200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
440 divided by 684 is 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 126483.1959
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 14:
684 can be fit into 4400 6 times, resulting in a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 126483.195906
The remainder is 296 after subtracting 4104 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
684 goes into 2960 4 times with a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 126483.1959064
Deduct 2736 from 2960 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 16:
The number 684 fits into 2240 3 times, leaving a remainder of 188.
The next digit of our result is 3. 
Result so far: 126483.19590643
Subtracting 2052 from 2240 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 126483.19590643 with a remainder of 1.88e-07.
