We're dividing 76788554 by 731 
The aim is to understand the frequency of 731 in 76788554.

On to step 1:
If we divide 7 by 731, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 731

Going ahead to step 2:
If we divide 76 by 731, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 731

Moving on to step 3:
When dividing 767 by 731, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 731 away from 767, we end up with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 731

On to step 4:
731 goes into 368 0 times with a remainder of 368.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 368 and we're left with 368.
Grab the next digit (8) from the dividend, add it to 368, then carry on: 3688 / 731

Let's proceed to step 5:
The number 731 fits into 3688 5 times, leaving a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 33 after subtracting 3655 from 3688.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 731

Moving on to step 6:
The number 731 fits into 335 0 times, leaving a remainder of 335.
Record the quotient 0 as the next digit in the result. 
Result so far: 1050.0
If we take 0 away from 335, we end up with 335.
Append the next digit (5) from the dividend to 335 and continue with: 3355 / 731

Moving on to step 7:
When dividing 3355 by 731, we get 4 with a remainder of 431.
The next digit of our result is 4. 
Result so far: 10504.0
The remainder is 431 after subtracting 2924 from 3355.
Fetch the next digit (4) from the dividend, attach it to 431 and continue: 4314 / 731

On to step 8:
4314 divided by 731 is 5 with a remainder of 659.
Put 5 as the next digit of the answer. 
Result so far: 105045.0
Deduct 3655 from 4314 and we're left with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Step 9:
If we divide 6590 by 731, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 105045.9
If we subtract 6579 from 6590, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 731, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 105045.9
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
When dividing 1100 by 731, we get 1 with a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 105045.901
Subtracting 731 from 1100 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 12:
If we divide 3690 by 731, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 105045.9015
The remainder is 35 after subtracting 3655 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 731, we get 0 and a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 105045.9015
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
The number 731 fits into 3500 4 times, leaving a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 105045.901504
Subtract 2924 from 3500 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 15:
731 goes into 5760 7 times with a remainder of 643.
Use 7 as the next digit of our solution. 
Result so far: 105045.9015047
Subtracting 5117 from 5760 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 16:
The number 731 fits into 6430 8 times, leaving a remainder of 582.
The next digit of our result is 8. 
Result so far: 105045.90150478
If we subtract 5848 from 6430, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

The final outcome is 105045.90150478, with a leftover of 5.82e-07.
