We're dividing 74937687 by 404 
The aim is to understand the frequency of 404 in 74937687.

Moving on to step 1:
The number 404 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 404

Moving on to step 2:
If we divide 74 by 404, we get 0 and a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 404

Going ahead to step 3:
749 divided by 404 is 1 with a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 404 from 749 and we're left with 345.
Bring next digit (3) of the dividend behind the 345 and repeat the process: 3453 / 404

On to step 4:
404 goes into 3453 8 times with a remainder of 221.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 3232 from 3453 leaves us with 221.
Include the next digit (7) from the dividend after 221, then repeat: 2217 / 404

Advancing to step 5:
If we divide 2217 by 404, we get 5 and a remainder of 197.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
If we subtract 2020 from 2217, we get 197.
Append the next digit (6) from the dividend to 197 and continue with: 1976 / 404

Advancing to step 6:
The number 404 fits into 1976 4 times, leaving a remainder of 360.
The next digit of our result is 4. 
Result so far: 1854.0
If we subtract 1616 from 1976, we get 360.
Append the next digit (8) from the dividend to 360 and continue with: 3608 / 404

Moving on to step 7:
The number 404 fits into 3608 8 times, leaving a remainder of 376.
The next digit of our result is 8. 
Result so far: 18548.0
Subtract 3232 from 3608 to get 376.
Grab the next digit (7) from the dividend, add it to 376, then carry on: 3767 / 404

Advancing to step 8:
404 can be fit into 3767 9 times, resulting in a remainder of 131.
The next digit of our result is 9. 
Result so far: 185489.0
Subtract 3636 from 3767 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
404 goes into 1310 3 times with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 185489.3
If we subtract 1212 from 1310, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
When dividing 980 by 404, we get 2 with a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 185489.32
If we take 808 away from 980, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
If we divide 1720 by 404, we get 4 and a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 185489.324
Subtracting 1616 from 1720 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 12:
The number 404 fits into 1040 2 times, leaving a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 185489.3242
If we take 808 away from 1040, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 13:
If we divide 2320 by 404, we get 5 and a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 185489.32425
If we take 2020 away from 2320, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
3000 divided by 404 is 7 with a remainder of 172.
Put 7 as the next digit of the answer. 
Result so far: 185489.324257
Subtract 2828 from 3000 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
1720 divided by 404 is 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 185489.3242574
Subtracting 1616 from 1720 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 16:
If we divide 1040 by 404, we get 2 and a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 185489.32425742
If we take 808 away from 1040, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 185489.32425742, and the remainder is 2.32e-07.
