99213891 divided by 928 
The aim is to understand the frequency of 928 in 99213891.

Going ahead to step 1:
928 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 928

Step 2:
If we divide 99 by 928, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 928

Let's proceed to step 3:
928 goes into 992 1 times with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 928 from 992 to get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 928

On to step 4:
If we divide 641 by 928, we get 0 and a remainder of 641.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 641 after subtracting 0 from 641.
Fetch the next digit (3) from the dividend, attach it to 641 and continue: 6413 / 928

Let's proceed to step 5:
The number 928 fits into 6413 6 times, leaving a remainder of 845.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we take 5568 away from 6413, we end up with 845.
Append the next digit (8) from the dividend to 845 and continue with: 8458 / 928

Step 6:
928 can be fit into 8458 9 times, resulting in a remainder of 106.
The next digit of our result is 9. 
Result so far: 1069.0
If we take 8352 away from 8458, we end up with 106.
Take the next digit (9) from the dividend and append it to 106, then repeat: 1069 / 928

Moving on to step 7:
When dividing 1069 by 928, we get 1 with a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 10691.0
If we subtract 928 from 1069, we get 141.
Take the next digit (1) from the dividend and append it to 141, then repeat: 1411 / 928

Let's proceed to step 8:
When dividing 1411 by 928, we get 1 with a remainder of 483.
Use 1 as the next digit of our solution. 
Result so far: 106911.0
If we take 928 away from 1411, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 9:
When dividing 4830 by 928, we get 5 with a remainder of 190.
The next digit of our result is 5. 
Result so far: 106911.5
Subtracting 4640 from 4830 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
928 goes into 1900 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 106911.52
Subtract 1856 from 1900 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
When dividing 440 by 928, we get 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 106911.52
If we subtract 0 from 440, 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 12:
The number 928 fits into 4400 4 times, leaving a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 106911.5204
Deduct 3712 from 4400 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 13:
928 can be fit into 6880 7 times, resulting in a remainder of 384.
The next digit of our result is 7. 
Result so far: 106911.52047
If we subtract 6496 from 6880, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 14:
928 can be fit into 3840 4 times, resulting in a remainder of 128.
The next digit of our result is 4. 
Result so far: 106911.520474
If we subtract 3712 from 3840, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
If we divide 1280 by 928, we get 1 and a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 106911.5204741
Subtracting 928 from 1280 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
When dividing 3520 by 928, we get 3 with a remainder of 736.
The next digit of our result is 3. 
Result so far: 106911.52047413
Deduct 2784 from 3520 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The quotient of the division is 106911.52047413, and the remainder is 7.36e-07.
