We look at the division of 50938500 by 722 
The aim is to understand the frequency of 722 in 50938500.

On to step 1:
5 divided by 722 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 722

Advancing to step 2:
722 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 722

Going ahead to step 3:
The number 722 fits into 509 0 times, leaving a remainder of 509.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 509 leaves us with 509.
Include the next digit (3) from the dividend after 509, then repeat: 5093 / 722

Advancing to step 4:
When dividing 5093 by 722, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 39 after subtracting 5054 from 5093.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 722

Let's proceed to step 5:
722 goes into 398 0 times with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we take 0 away from 398, we end up with 398.
Append the next digit (5) from the dividend to 398 and continue with: 3985 / 722

Step 6:
722 goes into 3985 5 times with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 705.0
Deduct 3610 from 3985 and we're left with 375.
Include the next digit (0) from the dividend after 375, then repeat: 3750 / 722

On to step 7:
3750 divided by 722 is 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 7055.0
The remainder is 140 after subtracting 3610 from 3750.
Fetch the next digit (0) from the dividend, attach it to 140 and continue: 1400 / 722

Step 8:
The number 722 fits into 1400 1 times, leaving a remainder of 678.
The next digit of our result is 1. 
Result so far: 70551.0
Subtract 722 from 1400 to 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.

Let's proceed to step 9:
6780 divided by 722 is 9 with a remainder of 282.
The number 9 becomes the next digit in our result. 
Result so far: 70551.9
If we subtract 6498 from 6780, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 10:
2820 divided by 722 is 3 with a remainder of 654.
The number 3 becomes the next digit in our result. 
Result so far: 70551.93
If we subtract 2166 from 2820, we 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.

Moving on to step 11:
722 can be fit into 6540 9 times, resulting in a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 70551.939
If we subtract 6498 from 6540, we 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 12:
722 can be fit into 420 0 times, resulting in a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 70551.939
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 13:
The number 722 fits into 4200 5 times, leaving a remainder of 590.
The number 5 becomes the next digit in our result. 
Result so far: 70551.93905
The remainder is 590 after subtracting 3610 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 14:
When dividing 5900 by 722, we get 8 with a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 70551.939058
Subtracting 5776 from 5900 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 15:
When dividing 1240 by 722, we get 1 with a remainder of 518.
Record the quotient 1 as the next digit in the result. 
Result so far: 70551.9390581
Subtract 722 from 1240 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 16:
722 goes into 5180 7 times with a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 70551.93905817
The remainder is 126 after subtracting 5054 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final result is 70551.93905817 with a remainder of 1.26e-07.
