Let's divide 74768999 by 990
The aim is to understand the frequency of 990 in 74768999.

Advancing to step 1:
990 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 990

Going ahead to step 2:
If we divide 74 by 990, we get 0 and a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 990

Moving on to step 3:
990 can be fit into 747 0 times, resulting in a remainder of 747.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 747, we end up with 747.
Grab the next digit (6) from the dividend, add it to 747, then carry on: 7476 / 990

Let's proceed to step 4:
990 can be fit into 7476 7 times, resulting in a remainder of 546.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 6930 from 7476 and we're left with 546.
Bring next digit (8) of the dividend behind the 546 and repeat the process: 5468 / 990

Advancing to step 5:
990 can be fit into 5468 5 times, resulting in a remainder of 518.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 4950 from 5468 to get 518.
Include the next digit (9) from the dividend after 518, then repeat: 5189 / 990

Let's proceed to step 6:
If we divide 5189 by 990, we get 5 and a remainder of 239.
Put 5 as the next digit of the answer. 
Result so far: 755.0
Deduct 4950 from 5189 and we're left with 239.
Include the next digit (9) from the dividend after 239, then repeat: 2399 / 990

Moving on to step 7:
When dividing 2399 by 990, we get 2 with a remainder of 419.
The number 2 becomes the next digit in our result. 
Result so far: 7552.0
If we subtract 1980 from 2399, we get 419.
Fetch the next digit (9) from the dividend, attach it to 419 and continue: 4199 / 990

Going ahead to step 8:
990 goes into 4199 4 times with a remainder of 239.
Write down 4 as next digit of the result. 
Result so far: 75524.0
Subtracting 3960 from 4199 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 9:
990 can be fit into 2390 2 times, resulting in a remainder of 410.
Record the quotient 2 as the next digit in the result. 
Result so far: 75524.2
Subtracting 1980 from 2390 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
The number 990 fits into 4100 4 times, leaving a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 75524.24
Subtract 3960 from 4100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 990 is 1 with a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 75524.241
The remainder is 410 after subtracting 990 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 12:
990 goes into 4100 4 times with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 75524.2414
The remainder is 140 after subtracting 3960 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
990 can be fit into 1400 1 times, resulting in a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 75524.24141
The remainder is 410 after subtracting 990 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 14:
4100 divided by 990 is 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 75524.241414
Subtract 3960 from 4100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 15:
990 can be fit into 1400 1 times, resulting in a remainder of 410.
The next digit of our result is 1. 
Result so far: 75524.2414141
Deduct 990 from 1400 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 16:
When dividing 4100 by 990, we get 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 75524.24141414
Subtracting 3960 from 4100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 75524.24141414, and the remainder is 1.4e-07.
