We're dividing 90502794 by 722 
The aim is to understand the frequency of 722 in 90502794.

Step 1:
When dividing 9 by 722, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 722

Going ahead to step 2:
When dividing 90 by 722, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 722

Going ahead to step 3:
When dividing 905 by 722, we get 1 with a remainder of 183.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 722 from 905 to get 183.
Take the next digit (0) from the dividend and append it to 183, then repeat: 1830 / 722

Step 4:
1830 divided by 722 is 2 with a remainder of 386.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1444 from 1830 and we're left with 386.
Grab the next digit (2) from the dividend, add it to 386, then carry on: 3862 / 722

Let's proceed to step 5:
When dividing 3862 by 722, we get 5 with a remainder of 252.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 3610 from 3862 and we're left with 252.
Bring next digit (7) of the dividend behind the 252 and repeat the process: 2527 / 722

Advancing to step 6:
2527 divided by 722 is 3 with a remainder of 361.
Put 3 as the next digit of the answer. 
Result so far: 1253.0
Deduct 2166 from 2527 and we're left with 361.
Take the next digit (9) from the dividend and append it to 361, then repeat: 3619 / 722

Advancing to step 7:
722 goes into 3619 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 12535.0
The remainder is 9 after subtracting 3610 from 3619.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 722

Advancing to step 8:
722 can be fit into 94 0 times, resulting in a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 125350.0
The remainder is 94 after subtracting 0 from 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
The number 722 fits into 940 1 times, leaving a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 125350.1
Subtracting 722 from 940 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 10:
2180 divided by 722 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 125350.13
The remainder is 14 after subtracting 2166 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
If we divide 140 by 722, we get 0 and a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 125350.13
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 722 is 1 with a remainder of 678.
The number 1 becomes the next digit in our result. 
Result so far: 125350.1301
If we subtract 722 from 1400, we get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 13:
If we divide 6780 by 722, we get 9 and a remainder of 282.
Record the quotient 9 as the next digit in the result. 
Result so far: 125350.13019
If we take 6498 away from 6780, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 14:
722 goes into 2820 3 times with a remainder of 654.
Put 3 as the next digit of the answer. 
Result so far: 125350.130193
Subtract 2166 from 2820 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 15:
6540 divided by 722 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 125350.1301939
Subtract 6498 from 6540 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
If we divide 420 by 722, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 125350.1301939
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 125350.1301939 with a balance of 4.2e-07.
