We look at the division of 3537917 by 966 
The aim is to understand the frequency of 966 in 3537917.

Step 1:
3 divided by 966 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 966

Going ahead to step 2:
966 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 966

Going ahead to step 3:
966 goes into 353 0 times with a remainder of 353.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 353, we get 353.
Append the next digit (7) from the dividend to 353 and continue with: 3537 / 966

Step 4:
The number 966 fits into 3537 3 times, leaving a remainder of 639.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2898 from 3537 and we're left with 639.
Append the next digit (9) from the dividend to 639 and continue with: 6399 / 966

On to step 5:
The number 966 fits into 6399 6 times, leaving a remainder of 603.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtracting 5796 from 6399 leaves us with 603.
Fetch the next digit (1) from the dividend, attach it to 603 and continue: 6031 / 966

Step 6:
966 goes into 6031 6 times with a remainder of 235.
The next digit of our result is 6. 
Result so far: 366.0
Subtract 5796 from 6031 to get 235.
Include the next digit (7) from the dividend after 235, then repeat: 2357 / 966

On to step 7:
966 can be fit into 2357 2 times, resulting in a remainder of 425.
The number 2 becomes the next digit in our result. 
Result so far: 3662.0
If we subtract 1932 from 2357, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 8:
When dividing 4250 by 966, we get 4 with a remainder of 386.
The next digit of our result is 4. 
Result so far: 3662.4
If we take 3864 away from 4250, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 9:
The number 966 fits into 3860 3 times, leaving a remainder of 962.
The number 3 becomes the next digit in our result. 
Result so far: 3662.43
Subtract 2898 from 3860 to get 962.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9620, and continue the process.

Step 10:
9620 divided by 966 is 9 with a remainder of 926.
Use 9 as the next digit of our solution. 
Result so far: 3662.439
If we subtract 8694 from 9620, we get 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

On to step 11:
966 goes into 9260 9 times with a remainder of 566.
Put 9 as the next digit of the answer. 
Result so far: 3662.4399
If we subtract 8694 from 9260, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

In conclusion, the division gives 3662.4399 with a balance of 0.00566.
