We divide 91681120 by 920
The aim is to understand the frequency of 920 in 91681120.

Advancing to step 1:
When dividing 9 by 920, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 920

Going ahead to step 2:
920 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (6) from the dividend, add it to 91, then carry on: 916 / 920

Moving on to step 3:
920 goes into 916 0 times with a remainder of 916.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 916 leaves us with 916.
Take the next digit (8) from the dividend and append it to 916, then repeat: 9168 / 920

Advancing to step 4:
920 goes into 9168 9 times with a remainder of 888.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8280 from 9168, we get 888.
Append the next digit (1) from the dividend to 888 and continue with: 8881 / 920

Advancing to step 5:
The number 920 fits into 8881 9 times, leaving a remainder of 601.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 8280 away from 8881, we end up with 601.
Fetch the next digit (1) from the dividend, attach it to 601 and continue: 6011 / 920

Moving on to step 6:
The number 920 fits into 6011 6 times, leaving a remainder of 491.
Put 6 as the next digit of the answer. 
Result so far: 996.0
If we take 5520 away from 6011, we end up with 491.
Grab the next digit (2) from the dividend, add it to 491, then carry on: 4912 / 920

Going ahead to step 7:
920 goes into 4912 5 times with a remainder of 312.
The next digit of our result is 5. 
Result so far: 9965.0
The remainder is 312 after subtracting 4600 from 4912.
Include the next digit (0) from the dividend after 312, then repeat: 3120 / 920

On to step 8:
920 goes into 3120 3 times with a remainder of 360.
Put 3 as the next digit of the answer. 
Result so far: 99653.0
Subtracting 2760 from 3120 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
3600 divided by 920 is 3 with a remainder of 840.
Put 3 as the next digit of the answer. 
Result so far: 99653.3
The remainder is 840 after subtracting 2760 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 10:
8400 divided by 920 is 9 with a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 99653.39
If we subtract 8280 from 8400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
920 goes into 1200 1 times with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 99653.391
The remainder is 280 after subtracting 920 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
If we divide 2800 by 920, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 99653.3913
If we take 2760 away from 2800, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
If we divide 400 by 920, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 99653.3913
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
The number 920 fits into 4000 4 times, leaving a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 99653.391304
Deduct 3680 from 4000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
When dividing 3200 by 920, we get 3 with a remainder of 440.
The next digit of our result is 3. 
Result so far: 99653.3913043
If we subtract 2760 from 3200, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 16:
920 goes into 4400 4 times with a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 99653.39130434
The remainder is 720 after subtracting 3680 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Our division results in 99653.39130434 with a remaining 7.2e-07.
