74178836 divided by 921 
The aim is to understand the frequency of 921 in 74178836.

Moving on to step 1:
The number 921 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 921

Going ahead to step 2:
When dividing 74 by 921, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 921

Let's proceed to step 3:
921 can be fit into 741 0 times, resulting in a remainder of 741.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 741 to get 741.
Grab the next digit (7) from the dividend, add it to 741, then carry on: 7417 / 921

Step 4:
7417 divided by 921 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7368 from 7417 to get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 921

Step 5:
If we divide 498 by 921, we get 0 and a remainder of 498.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 498, we end up with 498.
Grab the next digit (8) from the dividend, add it to 498, then carry on: 4988 / 921

Advancing to step 6:
4988 divided by 921 is 5 with a remainder of 383.
Use 5 as the next digit of our solution. 
Result so far: 805.0
Deduct 4605 from 4988 and we're left with 383.
Append the next digit (3) from the dividend to 383 and continue with: 3833 / 921

Step 7:
If we divide 3833 by 921, we get 4 and a remainder of 149.
The next digit of our result is 4. 
Result so far: 8054.0
The remainder is 149 after subtracting 3684 from 3833.
Append the next digit (6) from the dividend to 149 and continue with: 1496 / 921

On to step 8:
When dividing 1496 by 921, we get 1 with a remainder of 575.
Put 1 as the next digit of the answer. 
Result so far: 80541.0
The remainder is 575 after subtracting 921 from 1496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 9:
If we divide 5750 by 921, we get 6 and a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 80541.6
If we subtract 5526 from 5750, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
921 can be fit into 2240 2 times, resulting in a remainder of 398.
Record the quotient 2 as the next digit in the result. 
Result so far: 80541.62
Deduct 1842 from 2240 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 11:
921 goes into 3980 4 times with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 80541.624
Subtracting 3684 from 3980 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 12:
2960 divided by 921 is 3 with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 80541.6243
Deduct 2763 from 2960 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 13:
921 goes into 1970 2 times with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 80541.62432
Subtracting 1842 from 1970 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
921 goes into 1280 1 times with a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 80541.624321
If we subtract 921 from 1280, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 15:
3590 divided by 921 is 3 with a remainder of 827.
Record the quotient 3 as the next digit in the result. 
Result so far: 80541.6243213
If we subtract 2763 from 3590, we get 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Step 16:
921 goes into 8270 8 times with a remainder of 902.
Record the quotient 8 as the next digit in the result. 
Result so far: 80541.62432138
Deduct 7368 from 8270 and we're left with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

The quotient of the division is 80541.62432138, and the remainder is 9.02e-07.
