We look at the division of 104639 by 85 
We want to figure out the number of times 104639 can be divided by 85.

Going ahead to step 1:
1 divided by 85 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 85

Advancing to step 2:
10 divided by 85 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 85

Step 3:
85 can be fit into 104 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 85 from 104, we get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 85

Moving on to step 4:
196 divided by 85 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 170 from 196 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 85

Step 5:
When dividing 263 by 85, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 123.0
The remainder is 8 after subtracting 255 from 263.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 85

On to step 6:
If we divide 89 by 85, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1231.0
If we take 85 away from 89, 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.

Advancing to step 7:
40 divided by 85 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1231.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
85 goes into 400 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 1231.04
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
When dividing 600 by 85, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 1231.047
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1231.047
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 85, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1231.04705
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 1231.047058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
If we divide 700 by 85, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1231.0470588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1231.0470588 and a remainder of 2e-07.
