We look at the division of 66398 by 46 
The aim is to understand the frequency of 46 in 66398.

Step 1:
46 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 46

Let's proceed to step 2:
46 can be fit into 66 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 46 from 66 to get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 46

On to step 3:
When dividing 203 by 46, we get 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 184 from 203 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 46

Advancing to step 4:
46 goes into 199 4 times with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
Subtracting 184 from 199 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 46

On to step 5:
46 goes into 158 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1443.0
If we subtract 138 from 158, we get 20.
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 6:
46 goes into 200 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1443.4
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 46, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 1443.43
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
46 goes into 220 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1443.434
Subtracting 184 from 220 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 46, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1443.4347
Deduct 322 from 360 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
The number 46 fits into 380 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1443.43478
Deduct 368 from 380 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.

Going ahead to step 11:
46 goes into 120 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 1443.434782
Subtract 92 from 120 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
The number 46 fits into 280 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1443.4347826
The remainder is 4 after subtracting 276 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 46 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1443.4347826
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 1443.4347826, and the remainder is 4e-08.
