18043380 ÷ 992 
The aim is to understand the frequency of 992 in 18043380.

Step 1:
If we divide 1 by 992, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 992

Moving on to step 2:
If we divide 18 by 992, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 992

Let's proceed to step 3:
992 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Take the next digit (4) from the dividend and append it to 180, then repeat: 1804 / 992

Moving on to step 4:
When dividing 1804 by 992, we get 1 with a remainder of 812.
The next digit of our result is 1. 
Result so far: 1.0
If we take 992 away from 1804, we end up with 812.
Bring next digit (3) of the dividend behind the 812 and repeat the process: 8123 / 992

Step 5:
The number 992 fits into 8123 8 times, leaving a remainder of 187.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 7936 from 8123, we get 187.
Grab the next digit (3) from the dividend, add it to 187, then carry on: 1873 / 992

Moving on to step 6:
If we divide 1873 by 992, we get 1 and a remainder of 881.
The next digit of our result is 1. 
Result so far: 181.0
If we subtract 992 from 1873, we get 881.
Append the next digit (8) from the dividend to 881 and continue with: 8818 / 992

Moving on to step 7:
If we divide 8818 by 992, we get 8 and a remainder of 882.
Put 8 as the next digit of the answer. 
Result so far: 1818.0
Deduct 7936 from 8818 and we're left with 882.
Fetch the next digit (0) from the dividend, attach it to 882 and continue: 8820 / 992

Step 8:
992 can be fit into 8820 8 times, resulting in a remainder of 884.
Use 8 as the next digit of our solution. 
Result so far: 18188.0
Deduct 7936 from 8820 and we're left with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Moving on to step 9:
8840 divided by 992 is 8 with a remainder of 904.
Record the quotient 8 as the next digit in the result. 
Result so far: 18188.8
Subtracting 7936 from 8840 leaves us with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Moving on to step 10:
992 goes into 9040 9 times with a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 18188.89
If we take 8928 away from 9040, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
1120 divided by 992 is 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 18188.891
If we subtract 992 from 1120, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
1280 divided by 992 is 1 with a remainder of 288.
Write down 1 as next digit of the result. 
Result so far: 18188.8911
Subtracting 992 from 1280 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 18188.8911, with a leftover of 0.00288.
