Let's divide 921210 by 13
We're looking to find how many times 13 goes into 921210.

On to step 1:
9 divided by 13 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 13

Step 2:
13 goes into 92 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 91 from 92 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 13

On to step 3:
11 divided by 13 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we take 0 away from 11, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 13

Going ahead to step 4:
If we divide 112 by 13, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 708.0
If we subtract 104 from 112, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 13

Going ahead to step 5:
If we divide 81 by 13, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 7086.0
If we take 78 away from 81, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 13

Advancing to step 6:
13 goes into 30 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 70862.0
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.

On to step 7:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 70862.3
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 8:
10 divided by 13 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 70862.3
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.

Moving on to step 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 70862.307
If we take 91 away from 100, we end up with 9.
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 10:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 70862.3076
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.

Going ahead to step 11:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 70862.30769
If we take 117 away from 120, we end up 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.

Going ahead to step 12:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 70862.307692
If we take 26 away from 30, 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 13:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 70862.3076923
Subtracting 39 from 40 leaves us 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.

Advancing to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70862.3076923
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 70862.3076923 with a remaining 1e-08.
