We're dividing 27156240 by 661 
The aim is to understand the frequency of 661 in 27156240.

Advancing to step 1:
If we divide 2 by 661, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 661

Step 2:
661 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
If we take 0 away from 27, we end up with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 661

Step 3:
271 divided by 661 is 0 with a remainder of 271.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 271 after subtracting 0 from 271.
Include the next digit (5) from the dividend after 271, then repeat: 2715 / 661

Let's proceed to step 4:
When dividing 2715 by 661, we get 4 with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 2644 from 2715 leaves us with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 661

On to step 5:
If we divide 716 by 661, we get 1 and a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 661 from 716, we get 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 661

Step 6:
When dividing 552 by 661, we get 0 with a remainder of 552.
The next digit of our result is 0. 
Result so far: 410.0
If we take 0 away from 552, we end up with 552.
Bring next digit (4) of the dividend behind the 552 and repeat the process: 5524 / 661

Moving on to step 7:
The number 661 fits into 5524 8 times, leaving a remainder of 236.
Write down 8 as next digit of the result. 
Result so far: 4108.0
Subtracting 5288 from 5524 leaves us with 236.
Include the next digit (0) from the dividend after 236, then repeat: 2360 / 661

Step 8:
If we divide 2360 by 661, we get 3 and a remainder of 377.
The next digit of our result is 3. 
Result so far: 41083.0
Deduct 1983 from 2360 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Moving on to step 9:
The number 661 fits into 3770 5 times, leaving a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 41083.5
Deduct 3305 from 3770 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 10:
If we divide 4650 by 661, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 41083.57
The remainder is 23 after subtracting 4627 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
If we divide 230 by 661, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 41083.57
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
2300 divided by 661 is 3 with a remainder of 317.
The next digit of our result is 3. 
Result so far: 41083.5703
Deduct 1983 from 2300 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 13:
When dividing 3170 by 661, we get 4 with a remainder of 526.
The number 4 becomes the next digit in our result. 
Result so far: 41083.57034
The remainder is 526 after subtracting 2644 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 14:
The number 661 fits into 5260 7 times, leaving a remainder of 633.
The number 7 becomes the next digit in our result. 
Result so far: 41083.570347
If we take 4627 away from 5260, we end up with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Going ahead to step 15:
661 can be fit into 6330 9 times, resulting in a remainder of 381.
The next digit of our result is 9. 
Result so far: 41083.5703479
The remainder is 381 after subtracting 5949 from 6330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 16:
661 goes into 3810 5 times with a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 41083.57034795
Subtract 3305 from 3810 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Our division results in 41083.57034795 with a remaining 5.05e-07.
