74777331 divided by 754 
The aim is to understand the frequency of 754 in 74777331.

On to step 1:
754 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 754

Going ahead to step 2:
When dividing 74 by 754, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 754

Moving on to step 3:
747 divided by 754 is 0 with a remainder of 747.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 747 and we're left with 747.
Append the next digit (7) from the dividend to 747 and continue with: 7477 / 754

Let's proceed to step 4:
The number 754 fits into 7477 9 times, leaving a remainder of 691.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 6786 away from 7477, we end up with 691.
Fetch the next digit (7) from the dividend, attach it to 691 and continue: 6917 / 754

Step 5:
754 can be fit into 6917 9 times, resulting in a remainder of 131.
The next digit of our result is 9. 
Result so far: 99.0
If we take 6786 away from 6917, we end up with 131.
Fetch the next digit (3) from the dividend, attach it to 131 and continue: 1313 / 754

Let's proceed to step 6:
1313 divided by 754 is 1 with a remainder of 559.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
Deduct 754 from 1313 and we're left with 559.
Take the next digit (3) from the dividend and append it to 559, then repeat: 5593 / 754

Let's proceed to step 7:
The number 754 fits into 5593 7 times, leaving a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 9917.0
Subtracting 5278 from 5593 leaves us with 315.
Include the next digit (1) from the dividend after 315, then repeat: 3151 / 754

Step 8:
754 can be fit into 3151 4 times, resulting in a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 99174.0
The remainder is 135 after subtracting 3016 from 3151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
When dividing 1350 by 754, we get 1 with a remainder of 596.
Record the quotient 1 as the next digit in the result. 
Result so far: 99174.1
Deduct 754 from 1350 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
When dividing 5960 by 754, we get 7 with a remainder of 682.
Write down 7 as next digit of the result. 
Result so far: 99174.17
Deduct 5278 from 5960 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Moving on to step 11:
754 can be fit into 6820 9 times, resulting in a remainder of 34.
The next digit of our result is 9. 
Result so far: 99174.179
Subtracting 6786 from 6820 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
754 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 99174.179
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
754 can be fit into 3400 4 times, resulting in a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 99174.17904
Deduct 3016 from 3400 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 14:
If we divide 3840 by 754, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 99174.179045
Deduct 3770 from 3840 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 15:
754 goes into 700 0 times with a remainder of 700.
The next digit of our result is 0. 
Result so far: 99174.179045
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 16:
If we divide 7000 by 754, we get 9 and a remainder of 214.
Record the quotient 9 as the next digit in the result. 
Result so far: 99174.17904509
The remainder is 214 after subtracting 6786 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The final result is 99174.17904509 with a remainder of 2.14e-07.
