We're dividing 76930953 by 721 
The aim is to understand the frequency of 721 in 76930953.

Advancing to step 1:
The number 721 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 721

Step 2:
721 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 721

On to step 3:
721 goes into 769 1 times with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 721 away from 769, we end up with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 721

Step 4:
If we divide 483 by 721, we get 0 and a remainder of 483.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 483 to get 483.
Grab the next digit (0) from the dividend, add it to 483, then carry on: 4830 / 721

Advancing to step 5:
721 can be fit into 4830 6 times, resulting in a remainder of 504.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 4326 from 4830 to get 504.
Grab the next digit (9) from the dividend, add it to 504, then carry on: 5049 / 721

Let's proceed to step 6:
721 can be fit into 5049 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 1067.0
If we subtract 5047 from 5049, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 721

Let's proceed to step 7:
25 divided by 721 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 10670.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 721

Step 8:
721 can be fit into 253 0 times, resulting in a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 106700.0
The remainder is 253 after subtracting 0 from 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
When dividing 2530 by 721, we get 3 with a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 106700.3
Deduct 2163 from 2530 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 10:
721 can be fit into 3670 5 times, resulting in a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 106700.35
Subtract 3605 from 3670 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
721 can be fit into 650 0 times, resulting in a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 106700.35
Subtract 0 from 650 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 12:
When dividing 6500 by 721, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 106700.3509
Subtracting 6489 from 6500 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
110 divided by 721 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 106700.3509
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.

Advancing to step 14:
721 can be fit into 1100 1 times, resulting in a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 106700.350901
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 15:
The number 721 fits into 3790 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 106700.3509015
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.

Advancing to step 16:
If we divide 1850 by 721, we get 2 and a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 106700.35090152
Deduct 1442 from 1850 and we're left 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.

The final result is 106700.35090152 with a remainder of 4.08e-07.
