55721632 ÷ 721 
The aim is to understand the frequency of 721 in 55721632.

Let's proceed to step 1:
721 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 721

Moving on to step 2:
55 divided by 721 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 721

Going ahead to step 3:
557 divided by 721 is 0 with a remainder of 557.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 557, we get 557.
Fetch the next digit (2) from the dividend, attach it to 557 and continue: 5572 / 721

Moving on to step 4:
The number 721 fits into 5572 7 times, leaving a remainder of 525.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 525 after subtracting 5047 from 5572.
Bring next digit (1) of the dividend behind the 525 and repeat the process: 5251 / 721

Let's proceed to step 5:
721 goes into 5251 7 times with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 5047 from 5251 leaves us with 204.
Append the next digit (6) from the dividend to 204 and continue with: 2046 / 721

On to step 6:
If we divide 2046 by 721, we get 2 and a remainder of 604.
Write down 2 as next digit of the result. 
Result so far: 772.0
If we subtract 1442 from 2046, we get 604.
Append the next digit (3) from the dividend to 604 and continue with: 6043 / 721

Going ahead to step 7:
6043 divided by 721 is 8 with a remainder of 275.
Write down 8 as next digit of the result. 
Result so far: 7728.0
If we take 5768 away from 6043, we end up with 275.
Fetch the next digit (2) from the dividend, attach it to 275 and continue: 2752 / 721

On to step 8:
2752 divided by 721 is 3 with a remainder of 589.
Put 3 as the next digit of the answer. 
Result so far: 77283.0
If we take 2163 away from 2752, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Moving on to step 9:
5890 divided by 721 is 8 with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 77283.8
If we subtract 5768 from 5890, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
721 goes into 1220 1 times with a remainder of 499.
Write down 1 as next digit of the result. 
Result so far: 77283.81
The remainder is 499 after subtracting 721 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 11:
When dividing 4990 by 721, we get 6 with a remainder of 664.
The next digit of our result is 6. 
Result so far: 77283.816
Subtracting 4326 from 4990 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 12:
721 can be fit into 6640 9 times, resulting in a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 77283.8169
Subtract 6489 from 6640 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 13:
The number 721 fits into 1510 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 77283.81692
Deduct 1442 from 1510 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
680 divided by 721 is 0 with a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 77283.81692
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 15:
When dividing 6800 by 721, we get 9 with a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 77283.8169209
Deduct 6489 from 6800 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 16:
When dividing 3110 by 721, we get 4 with a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 77283.81692094
If we take 2884 away from 3110, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Our division results in 77283.81692094 with a remaining 2.26e-07.
