860104 divided by 13 
Our goal is to divide 860104 by 13.

Advancing to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 13

Step 2:
The number 13 fits into 86 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 8 after subtracting 78 from 86.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 13

Advancing to step 3:
If we divide 80 by 13, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 78 from 80 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 13

Moving on to step 4:
When dividing 21 by 13, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 661.0
If we take 13 away from 21, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 13

On to step 5:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6616.0
Subtracting 78 from 80 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 13

Moving on to step 6:
The number 13 fits into 24 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 66161.0
Deduct 13 from 24 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 66161.8
Subtract 104 from 110 to 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.

Advancing to step 8:
When dividing 60 by 13, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 66161.84
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66161.846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
20 divided by 13 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 66161.8461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 66161.84615
Subtracting 65 from 70 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 13, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 66161.846153
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 66161.8461538
Subtract 104 from 110 to 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.

On to step 14:
13 can be fit into 60 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 66161.84615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 66161.84615384, with a leftover of 8e-09.
