We're dividing 73453409 by 772 
The aim is to understand the frequency of 772 in 73453409.

Advancing to step 1:
When dividing 7 by 772, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 772

On to step 2:
73 divided by 772 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 772

Advancing to step 3:
If we divide 734 by 772, we get 0 and a remainder of 734.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 734, we end up with 734.
Fetch the next digit (5) from the dividend, attach it to 734 and continue: 7345 / 772

Advancing to step 4:
When dividing 7345 by 772, we get 9 with a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 6948 from 7345, we get 397.
Bring next digit (3) of the dividend behind the 397 and repeat the process: 3973 / 772

Going ahead to step 5:
When dividing 3973 by 772, we get 5 with a remainder of 113.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 3860 from 3973, we get 113.
Append the next digit (4) from the dividend to 113 and continue with: 1134 / 772

Step 6:
When dividing 1134 by 772, we get 1 with a remainder of 362.
The next digit of our result is 1. 
Result so far: 951.0
Deduct 772 from 1134 and we're left with 362.
Include the next digit (0) from the dividend after 362, then repeat: 3620 / 772

Let's proceed to step 7:
772 can be fit into 3620 4 times, resulting in a remainder of 532.
The next digit of our result is 4. 
Result so far: 9514.0
Subtracting 3088 from 3620 leaves us with 532.
Grab the next digit (9) from the dividend, add it to 532, then carry on: 5329 / 772

Going ahead to step 8:
772 can be fit into 5329 6 times, resulting in a remainder of 697.
Use 6 as the next digit of our solution. 
Result so far: 95146.0
If we subtract 4632 from 5329, we get 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

On to step 9:
772 goes into 6970 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 95146.9
Subtracting 6948 from 6970 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
When dividing 220 by 772, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 95146.9
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
When dividing 2200 by 772, we get 2 with a remainder of 656.
The number 2 becomes the next digit in our result. 
Result so far: 95146.902
The remainder is 656 after subtracting 1544 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

On to step 12:
772 can be fit into 6560 8 times, resulting in a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 95146.9028
If we take 6176 away from 6560, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 13:
772 can be fit into 3840 4 times, resulting in a remainder of 752.
The next digit of our result is 4. 
Result so far: 95146.90284
If we take 3088 away from 3840, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 14:
772 can be fit into 7520 9 times, resulting in a remainder of 572.
The next digit of our result is 9. 
Result so far: 95146.902849
Subtracting 6948 from 7520 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 15:
The number 772 fits into 5720 7 times, leaving a remainder of 316.
The number 7 becomes the next digit in our result. 
Result so far: 95146.9028497
Subtract 5404 from 5720 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 16:
772 goes into 3160 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 95146.90284974
Subtracting 3088 from 3160 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 95146.90284974 and a remainder of 7.2e-08.
