45867065 divided by 721 
The aim is to understand the frequency of 721 in 45867065.

Going ahead to step 1:
721 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 721

Let's proceed to step 2:
When dividing 45 by 721, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 721

Moving on to step 3:
458 divided by 721 is 0 with a remainder of 458.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 458 after subtracting 0 from 458.
Fetch the next digit (6) from the dividend, attach it to 458 and continue: 4586 / 721

On to step 4:
721 can be fit into 4586 6 times, resulting in a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 260 after subtracting 4326 from 4586.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 721

Going ahead to step 5:
When dividing 2607 by 721, we get 3 with a remainder of 444.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 2163 from 2607 to get 444.
Grab the next digit (0) from the dividend, add it to 444, then carry on: 4440 / 721

Advancing to step 6:
The number 721 fits into 4440 6 times, leaving a remainder of 114.
Write down 6 as next digit of the result. 
Result so far: 636.0
The remainder is 114 after subtracting 4326 from 4440.
Take the next digit (6) from the dividend and append it to 114, then repeat: 1146 / 721

Going ahead to step 7:
The number 721 fits into 1146 1 times, leaving a remainder of 425.
Put 1 as the next digit of the answer. 
Result so far: 6361.0
If we subtract 721 from 1146, we get 425.
Append the next digit (5) from the dividend to 425 and continue with: 4255 / 721

Going ahead to step 8:
If we divide 4255 by 721, we get 5 and a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 63615.0
Subtract 3605 from 4255 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 9:
If we divide 6500 by 721, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 63615.9
The remainder is 11 after subtracting 6489 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
721 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 63615.9
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
721 can be fit into 1100 1 times, resulting in a remainder of 379.
Record the quotient 1 as the next digit in the result. 
Result so far: 63615.901
If we subtract 721 from 1100, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 12:
When dividing 3790 by 721, we get 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 63615.9015
Deduct 3605 from 3790 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
When dividing 1850 by 721, we get 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 63615.90152
Subtracting 1442 from 1850 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 14:
4080 divided by 721 is 5 with a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 63615.901525
Subtracting 3605 from 4080 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 15:
4750 divided by 721 is 6 with a remainder of 424.
Use 6 as the next digit of our solution. 
Result so far: 63615.9015256
If we subtract 4326 from 4750, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 16:
When dividing 4240 by 721, we get 5 with a remainder of 635.
Use 5 as the next digit of our solution. 
Result so far: 63615.90152565
Subtracting 3605 from 4240 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

The final result is 63615.90152565 with a remainder of 6.35e-07.
