We divide 67372503 by 721
The aim is to understand the frequency of 721 in 67372503.

Advancing to step 1:
When dividing 6 by 721, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 721

On to step 2:
721 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 721

Advancing to step 3:
When dividing 673 by 721, we get 0 with a remainder of 673.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 673, we get 673.
Bring next digit (7) of the dividend behind the 673 and repeat the process: 6737 / 721

Moving on to step 4:
721 goes into 6737 9 times with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 6489 from 6737, we get 248.
Fetch the next digit (2) from the dividend, attach it to 248 and continue: 2482 / 721

Let's proceed to step 5:
If we divide 2482 by 721, we get 3 and a remainder of 319.
The next digit of our result is 3. 
Result so far: 93.0
If we take 2163 away from 2482, we end up with 319.
Bring next digit (5) of the dividend behind the 319 and repeat the process: 3195 / 721

On to step 6:
721 can be fit into 3195 4 times, resulting in a remainder of 311.
Use 4 as the next digit of our solution. 
Result so far: 934.0
If we subtract 2884 from 3195, we get 311.
Bring next digit (0) of the dividend behind the 311 and repeat the process: 3110 / 721

Step 7:
721 can be fit into 3110 4 times, resulting in a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 9344.0
If we subtract 2884 from 3110, we get 226.
Fetch the next digit (3) from the dividend, attach it to 226 and continue: 2263 / 721

Advancing to step 8:
2263 divided by 721 is 3 with a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 93443.0
Subtracting 2163 from 2263 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
The number 721 fits into 1000 1 times, leaving a remainder of 279.
Record the quotient 1 as the next digit in the result. 
Result so far: 93443.1
Subtracting 721 from 1000 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 10:
2790 divided by 721 is 3 with a remainder of 627.
Write down 3 as next digit of the result. 
Result so far: 93443.13
If we take 2163 away from 2790, we end up with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 11:
When dividing 6270 by 721, we get 8 with a remainder of 502.
Use 8 as the next digit of our solution. 
Result so far: 93443.138
Subtracting 5768 from 6270 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 12:
5020 divided by 721 is 6 with a remainder of 694.
The number 6 becomes the next digit in our result. 
Result so far: 93443.1386
Subtract 4326 from 5020 to get 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 13:
721 goes into 6940 9 times with a remainder of 451.
The next digit of our result is 9. 
Result so far: 93443.13869
The remainder is 451 after subtracting 6489 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 14:
When dividing 4510 by 721, we get 6 with a remainder of 184.
The next digit of our result is 6. 
Result so far: 93443.138696
The remainder is 184 after subtracting 4326 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 15:
721 can be fit into 1840 2 times, resulting in a remainder of 398.
The number 2 becomes the next digit in our result. 
Result so far: 93443.1386962
The remainder is 398 after subtracting 1442 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 16:
If we divide 3980 by 721, we get 5 and a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 93443.13869625
Subtracting 3605 from 3980 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final result is 93443.13869625 with a remainder of 3.75e-07.
