We're dividing 17216115 by 773 
The aim is to understand the frequency of 773 in 17216115.

Advancing to step 1:
The number 773 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 773

On to step 2:
When dividing 17 by 773, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 773

On to step 3:
If we divide 172 by 773, we get 0 and a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 172 leaves us with 172.
Bring next digit (1) of the dividend behind the 172 and repeat the process: 1721 / 773

Moving on to step 4:
If we divide 1721 by 773, we get 2 and a remainder of 175.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1546 from 1721 to get 175.
Take the next digit (6) from the dividend and append it to 175, then repeat: 1756 / 773

Going ahead to step 5:
If we divide 1756 by 773, we get 2 and a remainder of 210.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1546 from 1756, we get 210.
Append the next digit (1) from the dividend to 210 and continue with: 2101 / 773

Advancing to step 6:
When dividing 2101 by 773, we get 2 with a remainder of 555.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Deduct 1546 from 2101 and we're left with 555.
Grab the next digit (1) from the dividend, add it to 555, then carry on: 5551 / 773

On to step 7:
5551 divided by 773 is 7 with a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 2227.0
Deduct 5411 from 5551 and we're left with 140.
Include the next digit (5) from the dividend after 140, then repeat: 1405 / 773

On to step 8:
773 can be fit into 1405 1 times, resulting in a remainder of 632.
The number 1 becomes the next digit in our result. 
Result so far: 22271.0
Deduct 773 from 1405 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 9:
If we divide 6320 by 773, we get 8 and a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 22271.8
Subtract 6184 from 6320 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
1360 divided by 773 is 1 with a remainder of 587.
Use 1 as the next digit of our solution. 
Result so far: 22271.81
Subtract 773 from 1360 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Advancing to step 11:
773 can be fit into 5870 7 times, resulting in a remainder of 459.
The next digit of our result is 7. 
Result so far: 22271.817
If we subtract 5411 from 5870, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Moving on to step 12:
773 can be fit into 4590 5 times, resulting in a remainder of 725.
Record the quotient 5 as the next digit in the result. 
Result so far: 22271.8175
Subtract 3865 from 4590 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 13:
773 goes into 7250 9 times with a remainder of 293.
Record the quotient 9 as the next digit in the result. 
Result so far: 22271.81759
The remainder is 293 after subtracting 6957 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 14:
2930 divided by 773 is 3 with a remainder of 611.
The next digit of our result is 3. 
Result so far: 22271.817593
The remainder is 611 after subtracting 2319 from 2930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 15:
773 goes into 6110 7 times with a remainder of 699.
The number 7 becomes the next digit in our result. 
Result so far: 22271.8175937
The remainder is 699 after subtracting 5411 from 6110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 16:
When dividing 6990 by 773, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 22271.81759379
If we subtract 6957 from 6990, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 22271.81759379 with a remaining 3.3e-08.
