102861 divided by 85 
Our goal is to divide 102861 by 85.

Let's proceed to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 85

On to step 2:
10 divided by 85 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 85

Moving on to step 3:
When dividing 102 by 85, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 85 from 102.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 85

Let's proceed to step 4:
178 divided by 85 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 8 after subtracting 170 from 178.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 85

On to step 5:
85 goes into 86 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
The remainder is 1 after subtracting 85 from 86.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 85

On to step 6:
When dividing 11 by 85, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 1210.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
85 can be fit into 110 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1210.1
Subtract 85 from 110 to get 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 8:
250 divided by 85 is 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 1210.12
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
85 goes into 800 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 1210.129
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
If we divide 350 by 85, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1210.1294
Subtracting 340 from 350 leaves us 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.

Let's proceed to step 11:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1210.12941
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 85, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1210.129411
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 1210.129411 and a remainder of 6.5e-06.
