27175430 ÷ 418 
The aim is to understand the frequency of 418 in 27175430.

On to step 1:
The number 418 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 418

Advancing to step 2:
418 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 418

Advancing to step 3:
The number 418 fits into 271 0 times, leaving a remainder of 271.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 271 and we're left with 271.
Grab the next digit (7) from the dividend, add it to 271, then carry on: 2717 / 418

Going ahead to step 4:
2717 divided by 418 is 6 with a remainder of 209.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 209 after subtracting 2508 from 2717.
Grab the next digit (5) from the dividend, add it to 209, then carry on: 2095 / 418

Advancing to step 5:
If we divide 2095 by 418, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Deduct 2090 from 2095 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 418

Advancing to step 6:
The number 418 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 650.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 418

On to step 7:
If we divide 543 by 418, we get 1 and a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 6501.0
If we subtract 418 from 543, we get 125.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 418

Going ahead to step 8:
1250 divided by 418 is 2 with a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 65012.0
Deduct 836 from 1250 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 9:
The number 418 fits into 4140 9 times, leaving a remainder of 378.
The next digit of our result is 9. 
Result so far: 65012.9
If we subtract 3762 from 4140, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 10:
If we divide 3780 by 418, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 65012.99
Subtract 3762 from 3780 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 65012.99, with a leftover of 0.018.
