Let's divide 921397 by 10
We're looking to find how many times 10 goes into 921397.

Moving on to step 1:
If we divide 9 by 10, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 10

Moving on to step 2:
When dividing 92 by 10, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 90 from 92 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Moving on to step 3:
When dividing 21 by 10, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtract 20 from 21 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 10

Going ahead to step 4:
10 goes into 13 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 921.0
If we subtract 10 from 13, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 10

Going ahead to step 5:
10 goes into 39 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 9213.0
Subtract 30 from 39 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 10

Advancing to step 6:
10 goes into 97 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 92139.0
Subtracting 90 from 97 leaves us 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 7:
When dividing 70 by 10, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 92139.7
If we subtract 70 from 70, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 92139.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 92139.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 92139.7 with a remaining 0.0.
