We divide 837198 by 66
The aim is to understand the frequency of 66 in 837198.

Going ahead to step 1:
8 divided by 66 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 66

Advancing to step 2:
83 divided by 66 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 66 from 83 to get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 66

Advancing to step 3:
66 goes into 177 2 times with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 45 after subtracting 132 from 177.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 66

Going ahead to step 4:
If we divide 451 by 66, we get 6 and a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 126.0
Deduct 396 from 451 and we're left with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 66

On to step 5:
When dividing 559 by 66, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 1268.0
Deduct 528 from 559 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 66

Going ahead to step 6:
If we divide 318 by 66, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 12684.0
The remainder is 54 after subtracting 264 from 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
If we divide 540 by 66, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 12684.8
If we take 528 away from 540, we end up 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.

Advancing to step 8:
When dividing 120 by 66, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 12684.81
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12684.818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 66 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 12684.8181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12684.81818
Subtracting 528 from 540 leaves us 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 12:
When dividing 120 by 66, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 12684.818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12684.8181818
If we take 528 away from 540, we end up 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.

Advancing to step 14:
When dividing 120 by 66, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 12684.81818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 12684.81818181 with a remaining 5.4e-08.
