We divide 20910120 by 992
The aim is to understand the frequency of 992 in 20910120.

On to step 1:
When dividing 2 by 992, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 992

On to step 2:
992 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 992

Going ahead to step 3:
209 divided by 992 is 0 with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 992

Going ahead to step 4:
If we divide 2091 by 992, we get 2 and a remainder of 107.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1984 away from 2091, we end up with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 992

Going ahead to step 5:
992 goes into 1070 1 times with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 78 after subtracting 992 from 1070.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 992

Moving on to step 6:
The number 992 fits into 781 0 times, leaving a remainder of 781.
Use 0 as the next digit of our solution. 
Result so far: 210.0
Subtract 0 from 781 to get 781.
Grab the next digit (2) from the dividend, add it to 781, then carry on: 7812 / 992

Step 7:
992 can be fit into 7812 7 times, resulting in a remainder of 868.
The next digit of our result is 7. 
Result so far: 2107.0
If we take 6944 away from 7812, we end up with 868.
Append the next digit (0) from the dividend to 868 and continue with: 8680 / 992

Let's proceed to step 8:
The number 992 fits into 8680 8 times, leaving a remainder of 744.
The next digit of our result is 8. 
Result so far: 21078.0
Subtract 7936 from 8680 to get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 9:
992 goes into 7440 7 times with a remainder of 496.
The number 7 becomes the next digit in our result. 
Result so far: 21078.7
Subtract 6944 from 7440 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 10:
When dividing 4960 by 992, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 21078.75
Subtract 4960 from 4960 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.

On to step 11:
0 divided by 992 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21078.75
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.

Step 12:
0 divided by 992 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21078.75
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.

The quotient of the division is 21078.75, and the remainder is 0.0.
