Let's divide 35585399 by 721
The aim is to understand the frequency of 721 in 35585399.

Let's proceed to step 1:
The number 721 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 721

On to step 2:
The number 721 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 721

Moving on to step 3:
721 goes into 355 0 times with a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 355, we get 355.
Append the next digit (8) from the dividend to 355 and continue with: 3558 / 721

Moving on to step 4:
3558 divided by 721 is 4 with a remainder of 674.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2884 away from 3558, we end up with 674.
Take the next digit (5) from the dividend and append it to 674, then repeat: 6745 / 721

Step 5:
721 can be fit into 6745 9 times, resulting in a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 6489 away from 6745, we end up with 256.
Grab the next digit (3) from the dividend, add it to 256, then carry on: 2563 / 721

On to step 6:
When dividing 2563 by 721, we get 3 with a remainder of 400.
Write down 3 as next digit of the result. 
Result so far: 493.0
Subtract 2163 from 2563 to get 400.
Append the next digit (9) from the dividend to 400 and continue with: 4009 / 721

Advancing to step 7:
When dividing 4009 by 721, we get 5 with a remainder of 404.
Record the quotient 5 as the next digit in the result. 
Result so far: 4935.0
The remainder is 404 after subtracting 3605 from 4009.
Grab the next digit (9) from the dividend, add it to 404, then carry on: 4049 / 721

On to step 8:
When dividing 4049 by 721, we get 5 with a remainder of 444.
The next digit of our result is 5. 
Result so far: 49355.0
The remainder is 444 after subtracting 3605 from 4049.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 9:
721 goes into 4440 6 times with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 49355.6
If we take 4326 away from 4440, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
721 can be fit into 1140 1 times, resulting in a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 49355.61
If we take 721 away from 1140, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 11:
If we divide 4190 by 721, we get 5 and a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 49355.615
If we subtract 3605 from 4190, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 12:
5850 divided by 721 is 8 with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 49355.6158
The remainder is 82 after subtracting 5768 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
820 divided by 721 is 1 with a remainder of 99.
The next digit of our result is 1. 
Result so far: 49355.61581
Deduct 721 from 820 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 14:
990 divided by 721 is 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 49355.615811
Deduct 721 from 990 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Our division results in 49355.615811 with a remaining 2.69e-05.
