We're dividing 60847395 by 990 
The aim is to understand the frequency of 990 in 60847395.

On to step 1:
990 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 990

On to step 2:
When dividing 60 by 990, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 990

Moving on to step 3:
608 divided by 990 is 0 with a remainder of 608.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 608, we end up with 608.
Append the next digit (4) from the dividend to 608 and continue with: 6084 / 990

Moving on to step 4:
If we divide 6084 by 990, we get 6 and a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5940 away from 6084, we end up with 144.
Grab the next digit (7) from the dividend, add it to 144, then carry on: 1447 / 990

Moving on to step 5:
If we divide 1447 by 990, we get 1 and a remainder of 457.
The next digit of our result is 1. 
Result so far: 61.0
Deduct 990 from 1447 and we're left with 457.
Include the next digit (3) from the dividend after 457, then repeat: 4573 / 990

Step 6:
990 can be fit into 4573 4 times, resulting in a remainder of 613.
The number 4 becomes the next digit in our result. 
Result so far: 614.0
Subtracting 3960 from 4573 leaves us with 613.
Bring next digit (9) of the dividend behind the 613 and repeat the process: 6139 / 990

Advancing to step 7:
990 goes into 6139 6 times with a remainder of 199.
Record the quotient 6 as the next digit in the result. 
Result so far: 6146.0
If we take 5940 away from 6139, we end up with 199.
Include the next digit (5) from the dividend after 199, then repeat: 1995 / 990

Moving on to step 8:
1995 divided by 990 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 61462.0
If we take 1980 away from 1995, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 990 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 61462.0
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
990 can be fit into 1500 1 times, resulting in a remainder of 510.
The next digit of our result is 1. 
Result so far: 61462.01
The remainder is 510 after subtracting 990 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 11:
990 can be fit into 5100 5 times, resulting in a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 61462.015
If we take 4950 away from 5100, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
The number 990 fits into 1500 1 times, leaving a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 61462.0151
The remainder is 510 after subtracting 990 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 13:
990 goes into 5100 5 times with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 61462.01515
If we take 4950 away from 5100, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
When dividing 1500 by 990, we get 1 with a remainder of 510.
Use 1 as the next digit of our solution. 
Result so far: 61462.015151
Deduct 990 from 1500 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 15:
If we divide 5100 by 990, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 61462.0151515
If we take 4950 away from 5100, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
The number 990 fits into 1500 1 times, leaving a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 61462.01515151
If we take 990 away from 1500, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The final outcome is 61462.01515151, with a leftover of 5.1e-07.
