Let's divide 902140 by 10
The aim is to understand the frequency of 10 in 902140.

Advancing to step 1:
10 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 10

Going ahead to step 2:
90 divided by 10 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 90 from 90 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 10

Advancing to step 3:
10 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 10

Advancing to step 4:
10 can be fit into 21 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 902.0
Deduct 20 from 21 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 10

On to step 5:
10 goes into 14 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 9021.0
Deduct 10 from 14 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 10

Going ahead to step 6:
The number 10 fits into 40 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 90214.0
If we subtract 40 from 40, 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 7:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90214.0
Subtract 0 from 0 to 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.

Going ahead to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90214.0
Subtract 0 from 0 to 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.

In conclusion, the division gives 90214.0 with a balance of 0.0.
