Let's divide 78686664 by 471
The aim is to understand the frequency of 471 in 78686664.

Advancing to step 1:
The number 471 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 471

Let's proceed to step 2:
If we divide 78 by 471, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 471

Let's proceed to step 3:
471 can be fit into 786 1 times, resulting in a remainder of 315.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 471 away from 786, we end up with 315.
Grab the next digit (8) from the dividend, add it to 315, then carry on: 3158 / 471

Step 4:
471 can be fit into 3158 6 times, resulting in a remainder of 332.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2826 from 3158 and we're left with 332.
Grab the next digit (6) from the dividend, add it to 332, then carry on: 3326 / 471

On to step 5:
When dividing 3326 by 471, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 167.0
Deduct 3297 from 3326 and we're left with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 471

Going ahead to step 6:
471 can be fit into 296 0 times, resulting in a remainder of 296.
Record the quotient 0 as the next digit in the result. 
Result so far: 1670.0
If we take 0 away from 296, we end up with 296.
Take the next digit (6) from the dividend and append it to 296, then repeat: 2966 / 471

Step 7:
If we divide 2966 by 471, we get 6 and a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 16706.0
Deduct 2826 from 2966 and we're left with 140.
Fetch the next digit (4) from the dividend, attach it to 140 and continue: 1404 / 471

Let's proceed to step 8:
1404 divided by 471 is 2 with a remainder of 462.
Record the quotient 2 as the next digit in the result. 
Result so far: 167062.0
If we take 942 away from 1404, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 9:
When dividing 4620 by 471, we get 9 with a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 167062.9
If we take 4239 away from 4620, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 10:
When dividing 3810 by 471, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 167062.98
If we take 3768 away from 3810, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 471 is 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 167062.98
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
When dividing 4200 by 471, we get 8 with a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 167062.9808
If we subtract 3768 from 4200, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 13:
The number 471 fits into 4320 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 167062.98089
Deduct 4239 from 4320 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 14:
If we divide 810 by 471, we get 1 and a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 167062.980891
Subtracting 471 from 810 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 15:
If we divide 3390 by 471, we get 7 and a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 167062.9808917
Subtracting 3297 from 3390 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 16:
471 can be fit into 930 1 times, resulting in a remainder of 459.
Record the quotient 1 as the next digit in the result. 
Result so far: 167062.98089171
Deduct 471 from 930 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

The final outcome is 167062.98089171, with a leftover of 4.59e-07.
