We're dividing 68994359 by 921 
The aim is to understand the frequency of 921 in 68994359.

Advancing to step 1:
If we divide 6 by 921, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 921

On to step 2:
68 divided by 921 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 921

Step 3:
921 goes into 689 0 times with a remainder of 689.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 689 after subtracting 0 from 689.
Bring next digit (9) of the dividend behind the 689 and repeat the process: 6899 / 921

Advancing to step 4:
When dividing 6899 by 921, we get 7 with a remainder of 452.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 452 after subtracting 6447 from 6899.
Bring next digit (4) of the dividend behind the 452 and repeat the process: 4524 / 921

Moving on to step 5:
If we divide 4524 by 921, we get 4 and a remainder of 840.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 3684 from 4524 and we're left with 840.
Grab the next digit (3) from the dividend, add it to 840, then carry on: 8403 / 921

Moving on to step 6:
If we divide 8403 by 921, we get 9 and a remainder of 114.
The next digit of our result is 9. 
Result so far: 749.0
Deduct 8289 from 8403 and we're left with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 921

Advancing to step 7:
The number 921 fits into 1145 1 times, leaving a remainder of 224.
The number 1 becomes the next digit in our result. 
Result so far: 7491.0
Subtracting 921 from 1145 leaves us with 224.
Fetch the next digit (9) from the dividend, attach it to 224 and continue: 2249 / 921

Step 8:
2249 divided by 921 is 2 with a remainder of 407.
Put 2 as the next digit of the answer. 
Result so far: 74912.0
Subtract 1842 from 2249 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 9:
The number 921 fits into 4070 4 times, leaving a remainder of 386.
Record the quotient 4 as the next digit in the result. 
Result so far: 74912.4
If we subtract 3684 from 4070, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 10:
If we divide 3860 by 921, we get 4 and a remainder of 176.
The next digit of our result is 4. 
Result so far: 74912.44
If we subtract 3684 from 3860, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 74912.44 with a balance of 0.176.
