57158516 ÷ 722 
The aim is to understand the frequency of 722 in 57158516.

Step 1:
When dividing 5 by 722, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 722

Advancing to step 2:
722 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 722

On to step 3:
571 divided by 722 is 0 with a remainder of 571.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 571, we end up with 571.
Take the next digit (5) from the dividend and append it to 571, then repeat: 5715 / 722

Going ahead to step 4:
The number 722 fits into 5715 7 times, leaving a remainder of 661.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5054 from 5715 and we're left with 661.
Fetch the next digit (8) from the dividend, attach it to 661 and continue: 6618 / 722

On to step 5:
722 goes into 6618 9 times with a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 6498 from 6618 and we're left with 120.
Grab the next digit (5) from the dividend, add it to 120, then carry on: 1205 / 722

Advancing to step 6:
1205 divided by 722 is 1 with a remainder of 483.
Record the quotient 1 as the next digit in the result. 
Result so far: 791.0
Subtracting 722 from 1205 leaves us with 483.
Bring next digit (1) of the dividend behind the 483 and repeat the process: 4831 / 722

Advancing to step 7:
722 goes into 4831 6 times with a remainder of 499.
The next digit of our result is 6. 
Result so far: 7916.0
Deduct 4332 from 4831 and we're left with 499.
Fetch the next digit (6) from the dividend, attach it to 499 and continue: 4996 / 722

Step 8:
If we divide 4996 by 722, we get 6 and a remainder of 664.
Record the quotient 6 as the next digit in the result. 
Result so far: 79166.0
Subtracting 4332 from 4996 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 9:
If we divide 6640 by 722, we get 9 and a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 79166.9
Deduct 6498 from 6640 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 10:
722 goes into 1420 1 times with a remainder of 698.
Put 1 as the next digit of the answer. 
Result so far: 79166.91
If we subtract 722 from 1420, we get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Going ahead to step 11:
The number 722 fits into 6980 9 times, leaving a remainder of 482.
The next digit of our result is 9. 
Result so far: 79166.919
If we take 6498 away from 6980, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 12:
If we divide 4820 by 722, we get 6 and a remainder of 488.
Record the quotient 6 as the next digit in the result. 
Result so far: 79166.9196
Subtracting 4332 from 4820 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 13:
The number 722 fits into 4880 6 times, leaving a remainder of 548.
Write down 6 as next digit of the result. 
Result so far: 79166.91966
If we take 4332 away from 4880, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final outcome is 79166.91966, with a leftover of 0.000548.
