We divide 76729306 by 661
The aim is to understand the frequency of 661 in 76729306.

Advancing to step 1:
661 goes into 7 0 times 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.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 661

Going ahead to step 2:
76 divided by 661 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 661

Going ahead to step 3:
661 can be fit into 767 1 times, resulting in a remainder of 106.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 661 from 767 and we're left with 106.
Take the next digit (2) from the dividend and append it to 106, then repeat: 1062 / 661

Going ahead to step 4:
1062 divided by 661 is 1 with a remainder of 401.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 401 after subtracting 661 from 1062.
Bring next digit (9) of the dividend behind the 401 and repeat the process: 4019 / 661

Advancing to step 5:
4019 divided by 661 is 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtract 3966 from 4019 to get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 661

Moving on to step 6:
661 goes into 533 0 times with a remainder of 533.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
Deduct 0 from 533 and we're left with 533.
Bring next digit (0) of the dividend behind the 533 and repeat the process: 5330 / 661

Step 7:
The number 661 fits into 5330 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 11608.0
Subtracting 5288 from 5330 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 661

On to step 8:
The number 661 fits into 426 0 times, leaving a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 116080.0
If we take 0 away from 426, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
If we divide 4260 by 661, we get 6 and a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 116080.6
Deduct 3966 from 4260 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 10:
When dividing 2940 by 661, we get 4 with a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 116080.64
The remainder is 296 after subtracting 2644 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 11:
When dividing 2960 by 661, we get 4 with a remainder of 316.
The number 4 becomes the next digit in our result. 
Result so far: 116080.644
Subtract 2644 from 2960 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The quotient of the division is 116080.644, and the remainder is 0.0316.
