86644 divided by 39 
We want to figure out the number of times 86644 can be divided by 39.

On to step 1:
39 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
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 39

On to step 2:
When dividing 86 by 39, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 78 from 86 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 39

Let's proceed to step 3:
86 divided by 39 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 78 from 86 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 39

Going ahead to step 4:
When dividing 84 by 39, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 222.0
Deduct 78 from 84 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 39

Let's proceed to step 5:
If we divide 64 by 39, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 2221.0
Deduct 39 from 64 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 6:
If we divide 250 by 39, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 2221.6
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 39 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 2221.64
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 39, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2221.641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2221.641
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
39 goes into 100 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2221.64102
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2221.641025
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
250 divided by 39 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2221.6410256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
39 goes into 160 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 2221.64102564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 2221.64102564 with a remaining 4e-09.
