13867891 divided by 992 
The aim is to understand the frequency of 992 in 13867891.

Step 1:
992 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 992

Moving on to step 2:
992 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 992

Moving on to step 3:
When dividing 138 by 992, we get 0 with a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Bring next digit (6) of the dividend behind the 138 and repeat the process: 1386 / 992

On to step 4:
When dividing 1386 by 992, we get 1 with a remainder of 394.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 992 from 1386 to get 394.
Bring next digit (7) of the dividend behind the 394 and repeat the process: 3947 / 992

Advancing to step 5:
3947 divided by 992 is 3 with a remainder of 971.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 2976 from 3947 and we're left with 971.
Include the next digit (8) from the dividend after 971, then repeat: 9718 / 992

Step 6:
The number 992 fits into 9718 9 times, leaving a remainder of 790.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 8928 from 9718 and we're left with 790.
Bring next digit (9) of the dividend behind the 790 and repeat the process: 7909 / 992

Advancing to step 7:
If we divide 7909 by 992, we get 7 and a remainder of 965.
Write down 7 as next digit of the result. 
Result so far: 1397.0
Subtracting 6944 from 7909 leaves us with 965.
Take the next digit (1) from the dividend and append it to 965, then repeat: 9651 / 992

On to step 8:
9651 divided by 992 is 9 with a remainder of 723.
Use 9 as the next digit of our solution. 
Result so far: 13979.0
If we subtract 8928 from 9651, we get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Going ahead to step 9:
7230 divided by 992 is 7 with a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 13979.7
If we subtract 6944 from 7230, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 10:
992 goes into 2860 2 times with a remainder of 876.
Write down 2 as next digit of the result. 
Result so far: 13979.72
Subtracting 1984 from 2860 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Moving on to step 11:
When dividing 8760 by 992, we get 8 with a remainder of 824.
Use 8 as the next digit of our solution. 
Result so far: 13979.728
If we take 7936 away from 8760, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Moving on to step 12:
When dividing 8240 by 992, we get 8 with a remainder of 304.
The next digit of our result is 8. 
Result so far: 13979.7288
Deduct 7936 from 8240 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 13979.7288, with a leftover of 0.00304.
