We look at the division of 858703 by 39 
We're looking to find how many times 39 goes into 858703.

Advancing to step 1:
The number 39 fits into 8 0 times, leaving 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.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 39

Moving on to step 2:
39 can be fit into 85 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 7 after subtracting 78 from 85.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 39

Moving on to step 3:
When dividing 78 by 39, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 78 from 78 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 39

Moving on to step 4:
If we divide 7 by 39, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 39

Moving on to step 5:
39 can be fit into 70 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 2201.0
Subtracting 39 from 70 leaves us with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 39

Step 6:
If we divide 313 by 39, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 22018.0
If we take 312 away from 313, 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 7:
If we divide 10 by 39, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 22018.0
The remainder is 10 after subtracting 0 from 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 8:
39 can be fit into 100 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 22018.02
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 22018.025
Subtracting 195 from 220 leaves us 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.

Advancing to step 10:
250 divided by 39 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 22018.0256
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.

Going ahead to step 11:
When dividing 160 by 39, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 22018.02564
If we take 156 away from 160, we end up 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.

On to step 12:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 22018.025641
Deduct 39 from 40 and we're left 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.

Step 13:
When dividing 10 by 39, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22018.025641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
39 goes into 100 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 22018.02564102
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 22018.02564102, and the remainder is 2.2e-08.
