We're dividing 55170686 by 807 
The aim is to understand the frequency of 807 in 55170686.

Going ahead to step 1:
5 divided by 807 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 807

Moving on to step 2:
807 goes into 55 0 times 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.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 807

Moving on to step 3:
The number 807 fits into 551 0 times, leaving a remainder of 551.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 551 leaves us with 551.
Bring next digit (7) of the dividend behind the 551 and repeat the process: 5517 / 807

On to step 4:
When dividing 5517 by 807, we get 6 with a remainder of 675.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4842 from 5517 leaves us with 675.
Take the next digit (0) from the dividend and append it to 675, then repeat: 6750 / 807

Moving on to step 5:
The number 807 fits into 6750 8 times, leaving a remainder of 294.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 294 after subtracting 6456 from 6750.
Append the next digit (6) from the dividend to 294 and continue with: 2946 / 807

Going ahead to step 6:
The number 807 fits into 2946 3 times, leaving a remainder of 525.
Put 3 as the next digit of the answer. 
Result so far: 683.0
If we take 2421 away from 2946, we end up with 525.
Fetch the next digit (8) from the dividend, attach it to 525 and continue: 5258 / 807

Going ahead to step 7:
5258 divided by 807 is 6 with a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 6836.0
If we subtract 4842 from 5258, we get 416.
Take the next digit (6) from the dividend and append it to 416, then repeat: 4166 / 807

Let's proceed to step 8:
When dividing 4166 by 807, we get 5 with a remainder of 131.
Record the quotient 5 as the next digit in the result. 
Result so far: 68365.0
The remainder is 131 after subtracting 4035 from 4166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
807 can be fit into 1310 1 times, resulting in a remainder of 503.
Use 1 as the next digit of our solution. 
Result so far: 68365.1
If we subtract 807 from 1310, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 10:
If we divide 5030 by 807, we get 6 and a remainder of 188.
Put 6 as the next digit of the answer. 
Result so far: 68365.16
Subtract 4842 from 5030 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
1880 divided by 807 is 2 with a remainder of 266.
Put 2 as the next digit of the answer. 
Result so far: 68365.162
Subtract 1614 from 1880 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 12:
The number 807 fits into 2660 3 times, leaving a remainder of 239.
The next digit of our result is 3. 
Result so far: 68365.1623
Subtract 2421 from 2660 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 13:
The number 807 fits into 2390 2 times, leaving a remainder of 776.
Put 2 as the next digit of the answer. 
Result so far: 68365.16232
If we take 1614 away from 2390, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 14:
7760 divided by 807 is 9 with a remainder of 497.
Record the quotient 9 as the next digit in the result. 
Result so far: 68365.162329
The remainder is 497 after subtracting 7263 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 15:
If we divide 4970 by 807, we get 6 and a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 68365.1623296
If we subtract 4842 from 4970, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
1280 divided by 807 is 1 with a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 68365.16232961
Subtracting 807 from 1280 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

The final result is 68365.16232961 with a remainder of 4.73e-07.
