46879212 ÷ 721 
The aim is to understand the frequency of 721 in 46879212.

Advancing to step 1:
The number 721 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 721

Let's proceed to step 2:
If we divide 46 by 721, we get 0 and a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 721

Advancing to step 3:
The number 721 fits into 468 0 times, leaving a remainder of 468.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 468 and we're left with 468.
Fetch the next digit (7) from the dividend, attach it to 468 and continue: 4687 / 721

Going ahead to step 4:
When dividing 4687 by 721, we get 6 with a remainder of 361.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4326 from 4687 and we're left with 361.
Include the next digit (9) from the dividend after 361, then repeat: 3619 / 721

Step 5:
721 goes into 3619 5 times with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 3605 away from 3619, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 721

Moving on to step 6:
When dividing 142 by 721, we get 0 with a remainder of 142.
Write down 0 as next digit of the result. 
Result so far: 650.0
If we take 0 away from 142, we end up with 142.
Grab the next digit (1) from the dividend, add it to 142, then carry on: 1421 / 721

Moving on to step 7:
When dividing 1421 by 721, we get 1 with a remainder of 700.
The next digit of our result is 1. 
Result so far: 6501.0
Subtracting 721 from 1421 leaves us with 700.
Grab the next digit (2) from the dividend, add it to 700, then carry on: 7002 / 721

Step 8:
721 can be fit into 7002 9 times, resulting in a remainder of 513.
The next digit of our result is 9. 
Result so far: 65019.0
Subtract 6489 from 7002 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 9:
The number 721 fits into 5130 7 times, leaving a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 65019.7
Subtract 5047 from 5130 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 10:
830 divided by 721 is 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 65019.71
If we take 721 away from 830, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 11:
The number 721 fits into 1090 1 times, leaving a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 65019.711
The remainder is 369 after subtracting 721 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

After the division, we end up with 65019.711 and a remainder of 0.0369.
