73714123 divided by 661 
The aim is to understand the frequency of 661 in 73714123.

Step 1:
When dividing 7 by 661, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 661

Advancing to step 2:
The number 661 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 661

Let's proceed to step 3:
661 goes into 737 1 times with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 76 after subtracting 661 from 737.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 661

Moving on to step 4:
The number 661 fits into 761 1 times, leaving a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 661 from 761 leaves us with 100.
Include the next digit (4) from the dividend after 100, then repeat: 1004 / 661

On to step 5:
1004 divided by 661 is 1 with a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Subtracting 661 from 1004 leaves us with 343.
Include the next digit (1) from the dividend after 343, then repeat: 3431 / 661

Let's proceed to step 6:
661 goes into 3431 5 times with a remainder of 126.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
Deduct 3305 from 3431 and we're left with 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 661

On to step 7:
661 can be fit into 1262 1 times, resulting in a remainder of 601.
The next digit of our result is 1. 
Result so far: 11151.0
Subtract 661 from 1262 to get 601.
Append the next digit (3) from the dividend to 601 and continue with: 6013 / 661

Advancing to step 8:
661 goes into 6013 9 times with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 111519.0
Subtract 5949 from 6013 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
661 goes into 640 0 times with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 111519.0
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
When dividing 6400 by 661, we get 9 with a remainder of 451.
The next digit of our result is 9. 
Result so far: 111519.09
Subtract 5949 from 6400 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 11:
If we divide 4510 by 661, we get 6 and a remainder of 544.
Write down 6 as next digit of the result. 
Result so far: 111519.096
Deduct 3966 from 4510 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
When dividing 5440 by 661, we get 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 111519.0968
Deduct 5288 from 5440 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 13:
When dividing 1520 by 661, we get 2 with a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 111519.09682
If we take 1322 away from 1520, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 14:
661 can be fit into 1980 2 times, resulting in a remainder of 658.
Put 2 as the next digit of the answer. 
Result so far: 111519.096822
If we take 1322 away from 1980, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Our division results in 111519.096822 with a remaining 6.58e-05.
