We're dividing 55691040 by 966 
The aim is to understand the frequency of 966 in 55691040.

Step 1:
5 divided by 966 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 966

Let's proceed to step 2:
When dividing 55 by 966, we get 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 966

Let's proceed to step 3:
556 divided by 966 is 0 with a remainder of 556.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 556 leaves us with 556.
Include the next digit (9) from the dividend after 556, then repeat: 5569 / 966

Going ahead to step 4:
If we divide 5569 by 966, we get 5 and a remainder of 739.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4830 from 5569 and we're left with 739.
Bring next digit (1) of the dividend behind the 739 and repeat the process: 7391 / 966

Advancing to step 5:
If we divide 7391 by 966, we get 7 and a remainder of 629.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 6762 from 7391 leaves us with 629.
Append the next digit (0) from the dividend to 629 and continue with: 6290 / 966

Moving on to step 6:
966 can be fit into 6290 6 times, resulting in a remainder of 494.
Put 6 as the next digit of the answer. 
Result so far: 576.0
Subtracting 5796 from 6290 leaves us with 494.
Include the next digit (4) from the dividend after 494, then repeat: 4944 / 966

On to step 7:
966 goes into 4944 5 times with a remainder of 114.
Use 5 as the next digit of our solution. 
Result so far: 5765.0
If we take 4830 away from 4944, we end up with 114.
Bring next digit (0) of the dividend behind the 114 and repeat the process: 1140 / 966

Step 8:
966 goes into 1140 1 times with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 57651.0
If we take 966 away from 1140, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
1740 divided by 966 is 1 with a remainder of 774.
Put 1 as the next digit of the answer. 
Result so far: 57651.1
If we take 966 away from 1740, we end up with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Advancing to step 10:
966 can be fit into 7740 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 57651.18
Deduct 7728 from 7740 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 966 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 57651.18
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
The number 966 fits into 1200 1 times, leaving a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 57651.1801
If we subtract 966 from 1200, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 13:
966 can be fit into 2340 2 times, resulting in a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 57651.18012
Subtract 1932 from 2340 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 14:
If we divide 4080 by 966, we get 4 and a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 57651.180124
If we subtract 3864 from 4080, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
When dividing 2160 by 966, we get 2 with a remainder of 228.
The next digit of our result is 2. 
Result so far: 57651.1801242
Deduct 1932 from 2160 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 16:
If we divide 2280 by 966, we get 2 and a remainder of 348.
Use 2 as the next digit of our solution. 
Result so far: 57651.18012422
The remainder is 348 after subtracting 1932 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final outcome is 57651.18012422, with a leftover of 3.48e-07.
