We're dividing 55757021 by 755 
The aim is to understand the frequency of 755 in 55757021.

Advancing to step 1:
When dividing 5 by 755, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 755

Advancing to step 2:
755 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 755

Let's proceed to step 3:
If we divide 557 by 755, we get 0 and a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 557 to get 557.
Include the next digit (5) from the dividend after 557, then repeat: 5575 / 755

Moving on to step 4:
If we divide 5575 by 755, we get 7 and a remainder of 290.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5285 from 5575 leaves us with 290.
Take the next digit (7) from the dividend and append it to 290, then repeat: 2907 / 755

Advancing to step 5:
When dividing 2907 by 755, we get 3 with a remainder of 642.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtract 2265 from 2907 to get 642.
Append the next digit (0) from the dividend to 642 and continue with: 6420 / 755

Advancing to step 6:
When dividing 6420 by 755, we get 8 with a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 738.0
If we take 6040 away from 6420, we end up with 380.
Include the next digit (2) from the dividend after 380, then repeat: 3802 / 755

Going ahead to step 7:
755 can be fit into 3802 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 7385.0
Subtracting 3775 from 3802 leaves us with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 755

Let's proceed to step 8:
If we divide 271 by 755, we get 0 and a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 73850.0
The remainder is 271 after subtracting 0 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
The number 755 fits into 2710 3 times, leaving a remainder of 445.
Use 3 as the next digit of our solution. 
Result so far: 73850.3
If we take 2265 away from 2710, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 10:
755 can be fit into 4450 5 times, resulting in a remainder of 675.
The next digit of our result is 5. 
Result so far: 73850.35
The remainder is 675 after subtracting 3775 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Going ahead to step 11:
When dividing 6750 by 755, we get 8 with a remainder of 710.
Record the quotient 8 as the next digit in the result. 
Result so far: 73850.358
If we take 6040 away from 6750, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

On to step 12:
When dividing 7100 by 755, we get 9 with a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 73850.3589
If we take 6795 away from 7100, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 13:
3050 divided by 755 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 73850.35894
The remainder is 30 after subtracting 3020 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
755 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 73850.35894
Subtracting 0 from 300 leaves us 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.

Step 15:
3000 divided by 755 is 3 with a remainder of 735.
Put 3 as the next digit of the answer. 
Result so far: 73850.3589403
If we take 2265 away from 3000, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Going ahead to step 16:
755 can be fit into 7350 9 times, resulting in a remainder of 555.
Write down 9 as next digit of the result. 
Result so far: 73850.35894039
Subtracting 6795 from 7350 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The quotient of the division is 73850.35894039, and the remainder is 5.55e-07.
