We look at the division of 90540631 by 775 
The aim is to understand the frequency of 775 in 90540631.

Step 1:
If we divide 9 by 775, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 775

Let's proceed to step 2:
775 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 775

Step 3:
The number 775 fits into 905 1 times, leaving a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 130 after subtracting 775 from 905.
Take the next digit (4) from the dividend and append it to 130, then repeat: 1304 / 775

On to step 4:
The number 775 fits into 1304 1 times, leaving a remainder of 529.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 775 from 1304 to get 529.
Append the next digit (0) from the dividend to 529 and continue with: 5290 / 775

Advancing to step 5:
The number 775 fits into 5290 6 times, leaving a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 4650 away from 5290, we end up with 640.
Take the next digit (6) from the dividend and append it to 640, then repeat: 6406 / 775

Let's proceed to step 6:
If we divide 6406 by 775, we get 8 and a remainder of 206.
The next digit of our result is 8. 
Result so far: 1168.0
If we subtract 6200 from 6406, we get 206.
Grab the next digit (3) from the dividend, add it to 206, then carry on: 2063 / 775

Let's proceed to step 7:
775 can be fit into 2063 2 times, resulting in a remainder of 513.
Write down 2 as next digit of the result. 
Result so far: 11682.0
The remainder is 513 after subtracting 1550 from 2063.
Take the next digit (1) from the dividend and append it to 513, then repeat: 5131 / 775

Going ahead to step 8:
If we divide 5131 by 775, we get 6 and a remainder of 481.
Record the quotient 6 as the next digit in the result. 
Result so far: 116826.0
Subtracting 4650 from 5131 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Going ahead to step 9:
775 can be fit into 4810 6 times, resulting in a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 116826.6
If we subtract 4650 from 4810, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
When dividing 1600 by 775, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 116826.62
The remainder is 50 after subtracting 1550 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 775 fits into 500 0 times, leaving a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 116826.62
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 12:
When dividing 5000 by 775, we get 6 with a remainder of 350.
The next digit of our result is 6. 
Result so far: 116826.6206
Deduct 4650 from 5000 and we're left with 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 13:
3500 divided by 775 is 4 with a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 116826.62064
If we take 3100 away from 3500, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
If we divide 4000 by 775, we get 5 and a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 116826.620645
Subtracting 3875 from 4000 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 15:
775 can be fit into 1250 1 times, resulting in a remainder of 475.
Record the quotient 1 as the next digit in the result. 
Result so far: 116826.6206451
If we subtract 775 from 1250, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 16:
If we divide 4750 by 775, we get 6 and a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 116826.62064516
The remainder is 100 after subtracting 4650 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 116826.62064516, with a leftover of 1e-07.
