We're dividing 66914737 by 659 
The aim is to understand the frequency of 659 in 66914737.

Advancing to step 1:
6 divided by 659 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 659

On to step 2:
659 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 659

Step 3:
659 can be fit into 669 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 659 from 669 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 659

Moving on to step 4:
The number 659 fits into 101 0 times, leaving a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 101, we end up with 101.
Fetch the next digit (4) from the dividend, attach it to 101 and continue: 1014 / 659

On to step 5:
If we divide 1014 by 659, we get 1 and a remainder of 355.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 659 from 1014, we get 355.
Append the next digit (7) from the dividend to 355 and continue with: 3557 / 659

Moving on to step 6:
If we divide 3557 by 659, we get 5 and a remainder of 262.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
If we subtract 3295 from 3557, we get 262.
Fetch the next digit (3) from the dividend, attach it to 262 and continue: 2623 / 659

Step 7:
The number 659 fits into 2623 3 times, leaving a remainder of 646.
Record the quotient 3 as the next digit in the result. 
Result so far: 10153.0
Subtract 1977 from 2623 to get 646.
Fetch the next digit (7) from the dividend, attach it to 646 and continue: 6467 / 659

Let's proceed to step 8:
If we divide 6467 by 659, we get 9 and a remainder of 536.
Put 9 as the next digit of the answer. 
Result so far: 101539.0
If we subtract 5931 from 6467, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 9:
When dividing 5360 by 659, we get 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 101539.8
Subtract 5272 from 5360 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
The number 659 fits into 880 1 times, leaving a remainder of 221.
Put 1 as the next digit of the answer. 
Result so far: 101539.81
If we take 659 away from 880, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 11:
When dividing 2210 by 659, we get 3 with a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 101539.813
Subtract 1977 from 2210 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 12:
When dividing 2330 by 659, we get 3 with a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 101539.8133
Subtract 1977 from 2330 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

The final outcome is 101539.8133, with a leftover of 0.00353.
