We divide 861331 by 13
We want to divide 861331 by 13.

Advancing to step 1:
When dividing 8 by 13, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 13

On to step 2:
13 goes into 86 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 78 from 86, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 13

Going ahead to step 3:
If we divide 81 by 13, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 3 after subtracting 78 from 81.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 13

Going ahead to step 4:
13 can be fit into 33 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
If we subtract 26 from 33, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 13

Advancing to step 5:
The number 13 fits into 73 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 6625.0
Subtracting 65 from 73 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 13

Advancing to step 6:
13 goes into 81 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 66256.0
Subtract 78 from 81 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 13, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 66256.2
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 13 fits into 40 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 66256.23
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
13 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 66256.23
If we take 0 away from 10, we end up 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.

Advancing to step 10:
When dividing 100 by 13, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 66256.2307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
If we divide 90 by 13, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 66256.23076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
13 can be fit into 120 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 66256.230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 66256.2307692
Deduct 26 from 30 and we're left 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.

Let's proceed to step 14:
13 goes into 40 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 66256.23076923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 66256.23076923 and a remainder of 1e-09.
