Let's divide 71437639 by 722
The aim is to understand the frequency of 722 in 71437639.

On to step 1:
When dividing 7 by 722, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 722

Moving on to step 2:
When dividing 71 by 722, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 722

Let's proceed to step 3:
722 can be fit into 714 0 times, resulting in a remainder of 714.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 714 and we're left with 714.
Take the next digit (3) from the dividend and append it to 714, then repeat: 7143 / 722

Going ahead to step 4:
When dividing 7143 by 722, we get 9 with a remainder of 645.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6498 from 7143 to get 645.
Take the next digit (7) from the dividend and append it to 645, then repeat: 6457 / 722

Going ahead to step 5:
If we divide 6457 by 722, we get 8 and a remainder of 681.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we subtract 5776 from 6457, we get 681.
Include the next digit (6) from the dividend after 681, then repeat: 6816 / 722

Going ahead to step 6:
722 can be fit into 6816 9 times, resulting in a remainder of 318.
Put 9 as the next digit of the answer. 
Result so far: 989.0
Subtracting 6498 from 6816 leaves us with 318.
Grab the next digit (3) from the dividend, add it to 318, then carry on: 3183 / 722

Moving on to step 7:
When dividing 3183 by 722, we get 4 with a remainder of 295.
The next digit of our result is 4. 
Result so far: 9894.0
If we take 2888 away from 3183, we end up with 295.
Include the next digit (9) from the dividend after 295, then repeat: 2959 / 722

Step 8:
If we divide 2959 by 722, we get 4 and a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 98944.0
Subtract 2888 from 2959 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
722 can be fit into 710 0 times, resulting in a remainder of 710.
The number 0 becomes the next digit in our result. 
Result so far: 98944.0
Subtract 0 from 710 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 10:
7100 divided by 722 is 9 with a remainder of 602.
The next digit of our result is 9. 
Result so far: 98944.09
If we subtract 6498 from 7100, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 11:
When dividing 6020 by 722, we get 8 with a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 98944.098
Subtract 5776 from 6020 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 12:
722 goes into 2440 3 times with a remainder of 274.
Put 3 as the next digit of the answer. 
Result so far: 98944.0983
The remainder is 274 after subtracting 2166 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 13:
The number 722 fits into 2740 3 times, leaving a remainder of 574.
Use 3 as the next digit of our solution. 
Result so far: 98944.09833
The remainder is 574 after subtracting 2166 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Our division results in 98944.09833 with a remaining 0.000574.
