We look at the division of 79594731 by 661 
The aim is to understand the frequency of 661 in 79594731.

Step 1:
When dividing 7 by 661, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 661

Step 2:
661 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 661

Let's proceed to step 3:
661 goes into 795 1 times with a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 661 from 795 and we're left with 134.
Fetch the next digit (9) from the dividend, attach it to 134 and continue: 1349 / 661

Advancing to step 4:
661 can be fit into 1349 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1322 from 1349 leaves us with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 661

On to step 5:
661 can be fit into 274 0 times, resulting in a remainder of 274.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 274 leaves us with 274.
Take the next digit (7) from the dividend and append it to 274, then repeat: 2747 / 661

Moving on to step 6:
2747 divided by 661 is 4 with a remainder of 103.
Write down 4 as next digit of the result. 
Result so far: 1204.0
Subtract 2644 from 2747 to get 103.
Bring next digit (3) of the dividend behind the 103 and repeat the process: 1033 / 661

Going ahead to step 7:
661 goes into 1033 1 times with a remainder of 372.
The number 1 becomes the next digit in our result. 
Result so far: 12041.0
Subtracting 661 from 1033 leaves us with 372.
Take the next digit (1) from the dividend and append it to 372, then repeat: 3721 / 661

Let's proceed to step 8:
661 goes into 3721 5 times with a remainder of 416.
The next digit of our result is 5. 
Result so far: 120415.0
Subtracting 3305 from 3721 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 9:
When dividing 4160 by 661, we get 6 with a remainder of 194.
Record the quotient 6 as the next digit in the result. 
Result so far: 120415.6
Deduct 3966 from 4160 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 10:
661 goes into 1940 2 times with a remainder of 618.
The next digit of our result is 2. 
Result so far: 120415.62
If we take 1322 away from 1940, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 11:
6180 divided by 661 is 9 with a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 120415.629
If we subtract 5949 from 6180, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 12:
661 goes into 2310 3 times with a remainder of 327.
The next digit of our result is 3. 
Result so far: 120415.6293
If we subtract 1983 from 2310, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 13:
When dividing 3270 by 661, we get 4 with a remainder of 626.
Use 4 as the next digit of our solution. 
Result so far: 120415.62934
The remainder is 626 after subtracting 2644 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 14:
If we divide 6260 by 661, we get 9 and a remainder of 311.
Put 9 as the next digit of the answer. 
Result so far: 120415.629349
If we take 5949 away from 6260, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 15:
661 can be fit into 3110 4 times, resulting in a remainder of 466.
Use 4 as the next digit of our solution. 
Result so far: 120415.6293494
Subtracting 2644 from 3110 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 16:
If we divide 4660 by 661, we get 7 and a remainder of 33.
The next digit of our result is 7. 
Result so far: 120415.62934947
Deduct 4627 from 4660 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 120415.62934947, and the remainder is 3.3e-08.
