We divide 97789631 by 966
The aim is to understand the frequency of 966 in 97789631.

Going ahead to step 1:
When dividing 9 by 966, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 966

Moving on to step 2:
When dividing 97 by 966, we get 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 966

Going ahead to step 3:
If we divide 977 by 966, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 966 from 977 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 966

Moving on to step 4:
When dividing 118 by 966, we get 0 with a remainder of 118.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 118 after subtracting 0 from 118.
Grab the next digit (9) from the dividend, add it to 118, then carry on: 1189 / 966

Advancing to step 5:
When dividing 1189 by 966, we get 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 966 from 1189 and we're left with 223.
Take the next digit (6) from the dividend and append it to 223, then repeat: 2236 / 966

Advancing to step 6:
When dividing 2236 by 966, we get 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 1012.0
Subtract 1932 from 2236 to get 304.
Take the next digit (3) from the dividend and append it to 304, then repeat: 3043 / 966

Let's proceed to step 7:
When dividing 3043 by 966, we get 3 with a remainder of 145.
The next digit of our result is 3. 
Result so far: 10123.0
Subtract 2898 from 3043 to get 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 966

Going ahead to step 8:
When dividing 1451 by 966, we get 1 with a remainder of 485.
Use 1 as the next digit of our solution. 
Result so far: 101231.0
If we take 966 away from 1451, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 9:
4850 divided by 966 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 101231.5
The remainder is 20 after subtracting 4830 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 966 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 101231.5
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
When dividing 2000 by 966, we get 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 101231.502
Deduct 1932 from 2000 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
680 divided by 966 is 0 with a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 101231.502
If we subtract 0 from 680, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 13:
966 can be fit into 6800 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 101231.50207
The remainder is 38 after subtracting 6762 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
966 can be fit into 380 0 times, resulting in a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 101231.50207
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 15:
If we divide 3800 by 966, we get 3 and a remainder of 902.
Use 3 as the next digit of our solution. 
Result so far: 101231.5020703
The remainder is 902 after subtracting 2898 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

Step 16:
If we divide 9020 by 966, we get 9 and a remainder of 326.
Record the quotient 9 as the next digit in the result. 
Result so far: 101231.50207039
If we take 8694 away from 9020, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

The final result is 101231.50207039 with a remainder of 3.26e-07.
