We're dividing 871644 by 39 
Let's see how many times 39 fits into 871644.

Advancing to step 1:
39 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 39

Advancing to step 2:
If we divide 87 by 39, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 78 from 87 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 39

Moving on to step 3:
When dividing 91 by 39, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 78 away from 91, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 39

Advancing to step 4:
39 can be fit into 136 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 223.0
Subtract 117 from 136 to get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 39

Moving on to step 5:
When dividing 194 by 39, we get 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 2234.0
Subtracting 156 from 194 leaves us with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 39

On to step 6:
39 can be fit into 384 9 times, resulting in a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 22349.0
Deduct 351 from 384 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
39 can be fit into 330 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 22349.8
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 22349.84
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
240 divided by 39 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 22349.846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
39 goes into 60 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 22349.8461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
39 can be fit into 210 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22349.84615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 22349.846153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
When dividing 330 by 39, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 22349.8461538
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
If we divide 180 by 39, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 22349.84615384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 22349.84615384 with a balance of 2.4e-08.
