Let's divide 28631451 by 722
The aim is to understand the frequency of 722 in 28631451.

Going ahead to step 1:
The number 722 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 722

Advancing to step 2:
28 divided by 722 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 722

Advancing to step 3:
If we divide 286 by 722, we get 0 and a remainder of 286.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 286 to get 286.
Bring next digit (3) of the dividend behind the 286 and repeat the process: 2863 / 722

Going ahead to step 4:
When dividing 2863 by 722, we get 3 with a remainder of 697.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2166 from 2863 leaves us with 697.
Take the next digit (1) from the dividend and append it to 697, then repeat: 6971 / 722

Step 5:
6971 divided by 722 is 9 with a remainder of 473.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 6498 from 6971 to get 473.
Fetch the next digit (4) from the dividend, attach it to 473 and continue: 4734 / 722

Step 6:
When dividing 4734 by 722, we get 6 with a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 396.0
Subtract 4332 from 4734 to get 402.
Take the next digit (5) from the dividend and append it to 402, then repeat: 4025 / 722

Going ahead to step 7:
722 goes into 4025 5 times with a remainder of 415.
The next digit of our result is 5. 
Result so far: 3965.0
The remainder is 415 after subtracting 3610 from 4025.
Bring next digit (1) of the dividend behind the 415 and repeat the process: 4151 / 722

On to step 8:
When dividing 4151 by 722, we get 5 with a remainder of 541.
Put 5 as the next digit of the answer. 
Result so far: 39655.0
Subtract 3610 from 4151 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 9:
5410 divided by 722 is 7 with a remainder of 356.
Record the quotient 7 as the next digit in the result. 
Result so far: 39655.7
If we subtract 5054 from 5410, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
3560 divided by 722 is 4 with a remainder of 672.
Use 4 as the next digit of our solution. 
Result so far: 39655.74
Subtract 2888 from 3560 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Advancing to step 11:
6720 divided by 722 is 9 with a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 39655.749
Subtract 6498 from 6720 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 12:
2220 divided by 722 is 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 39655.7493
If we subtract 2166 from 2220, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
722 can be fit into 540 0 times, resulting in a remainder of 540.
The next digit of our result is 0. 
Result so far: 39655.7493
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
The number 722 fits into 5400 7 times, leaving a remainder of 346.
The next digit of our result is 7. 
Result so far: 39655.749307
Deduct 5054 from 5400 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 15:
If we divide 3460 by 722, we get 4 and a remainder of 572.
Record the quotient 4 as the next digit in the result. 
Result so far: 39655.7493074
Deduct 2888 from 3460 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 16:
The number 722 fits into 5720 7 times, leaving a remainder of 666.
Record the quotient 7 as the next digit in the result. 
Result so far: 39655.74930747
Subtract 5054 from 5720 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

After the division, we end up with 39655.74930747 and a remainder of 6.66e-07.
