We look at the division of 61424622 by 661 
The aim is to understand the frequency of 661 in 61424622.

Moving on to step 1:
6 divided by 661 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 661

Moving on to step 2:
When dividing 61 by 661, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Fetch the next digit (4) from the dividend, attach it to 61 and continue: 614 / 661

Moving on to step 3:
The number 661 fits into 614 0 times, leaving a remainder of 614.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 614 after subtracting 0 from 614.
Fetch the next digit (2) from the dividend, attach it to 614 and continue: 6142 / 661

Let's proceed to step 4:
6142 divided by 661 is 9 with a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 193 after subtracting 5949 from 6142.
Append the next digit (4) from the dividend to 193 and continue with: 1934 / 661

On to step 5:
661 goes into 1934 2 times with a remainder of 612.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Deduct 1322 from 1934 and we're left with 612.
Include the next digit (6) from the dividend after 612, then repeat: 6126 / 661

Going ahead to step 6:
If we divide 6126 by 661, we get 9 and a remainder of 177.
Put 9 as the next digit of the answer. 
Result so far: 929.0
If we take 5949 away from 6126, we end up with 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 661

Moving on to step 7:
The number 661 fits into 1772 2 times, leaving a remainder of 450.
The next digit of our result is 2. 
Result so far: 9292.0
Subtracting 1322 from 1772 leaves us with 450.
Bring next digit (2) of the dividend behind the 450 and repeat the process: 4502 / 661

Step 8:
When dividing 4502 by 661, we get 6 with a remainder of 536.
The number 6 becomes the next digit in our result. 
Result so far: 92926.0
Subtract 3966 from 4502 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 9:
661 can be fit into 5360 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 92926.8
Subtract 5288 from 5360 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
720 divided by 661 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 92926.81
Deduct 661 from 720 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
The number 661 fits into 590 0 times, leaving a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 92926.81
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 12:
If we divide 5900 by 661, we get 8 and a remainder of 612.
Record the quotient 8 as the next digit in the result. 
Result so far: 92926.8108
If we take 5288 away from 5900, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 13:
6120 divided by 661 is 9 with a remainder of 171.
Put 9 as the next digit of the answer. 
Result so far: 92926.81089
Deduct 5949 from 6120 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 14:
661 goes into 1710 2 times with a remainder of 388.
The next digit of our result is 2. 
Result so far: 92926.810892
If we subtract 1322 from 1710, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 15:
When dividing 3880 by 661, we get 5 with a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 92926.8108925
If we subtract 3305 from 3880, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 16:
If we divide 5750 by 661, we get 8 and a remainder of 462.
Put 8 as the next digit of the answer. 
Result so far: 92926.81089258
Subtracting 5288 from 5750 leaves us 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.

The final outcome is 92926.81089258, with a leftover of 4.62e-07.
