We look at the division of 990518 by 46 
The aim is to understand the frequency of 46 in 990518.

Going ahead to step 1:
If we divide 9 by 46, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 46

Step 2:
The number 46 fits into 99 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 92 from 99 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 46

Moving on to step 3:
46 can be fit into 70 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 46 away from 70, we end up with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 46

Moving on to step 4:
When dividing 245 by 46, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 215.0
Subtract 230 from 245 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 46

Step 5:
46 can be fit into 151 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 2153.0
Deduct 138 from 151 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 46

Going ahead to step 6:
46 can be fit into 138 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 21533.0
Deduct 138 from 138 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 46 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21533.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 46 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21533.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 21533.0 with a balance of 0.0.
