18099697 divided by 981 
The aim is to understand the frequency of 981 in 18099697.

Moving on to step 1:
If we divide 1 by 981, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 981

Step 2:
981 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 981

Let's proceed to step 3:
If we divide 180 by 981, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 180, we get 180.
Fetch the next digit (9) from the dividend, attach it to 180 and continue: 1809 / 981

Moving on to step 4:
If we divide 1809 by 981, we get 1 and a remainder of 828.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 981 from 1809 to get 828.
Append the next digit (9) from the dividend to 828 and continue with: 8289 / 981

Moving on to step 5:
8289 divided by 981 is 8 with a remainder of 441.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 7848 from 8289 and we're left with 441.
Grab the next digit (6) from the dividend, add it to 441, then carry on: 4416 / 981

Moving on to step 6:
When dividing 4416 by 981, we get 4 with a remainder of 492.
Write down 4 as next digit of the result. 
Result so far: 184.0
The remainder is 492 after subtracting 3924 from 4416.
Include the next digit (9) from the dividend after 492, then repeat: 4929 / 981

Advancing to step 7:
When dividing 4929 by 981, we get 5 with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 1845.0
If we take 4905 away from 4929, we end up with 24.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 981

Advancing to step 8:
When dividing 247 by 981, we get 0 with a remainder of 247.
Use 0 as the next digit of our solution. 
Result so far: 18450.0
If we take 0 away from 247, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 9:
If we divide 2470 by 981, we get 2 and a remainder of 508.
Use 2 as the next digit of our solution. 
Result so far: 18450.2
Deduct 1962 from 2470 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 10:
981 goes into 5080 5 times with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 18450.25
Subtract 4905 from 5080 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
When dividing 1750 by 981, we get 1 with a remainder of 769.
The next digit of our result is 1. 
Result so far: 18450.251
Deduct 981 from 1750 and we're left with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Step 12:
When dividing 7690 by 981, we get 7 with a remainder of 823.
Put 7 as the next digit of the answer. 
Result so far: 18450.2517
If we take 6867 away from 7690, we end up with 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Let's proceed to step 13:
The number 981 fits into 8230 8 times, leaving a remainder of 382.
Use 8 as the next digit of our solution. 
Result so far: 18450.25178
If we take 7848 away from 8230, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 14:
When dividing 3820 by 981, we get 3 with a remainder of 877.
The next digit of our result is 3. 
Result so far: 18450.251783
Subtract 2943 from 3820 to get 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

Let's proceed to step 15:
981 goes into 8770 8 times with a remainder of 922.
Put 8 as the next digit of the answer. 
Result so far: 18450.2517838
Subtract 7848 from 8770 to get 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Let's proceed to step 16:
981 can be fit into 9220 9 times, resulting in a remainder of 391.
Use 9 as the next digit of our solution. 
Result so far: 18450.25178389
Deduct 8829 from 9220 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The quotient of the division is 18450.25178389, and the remainder is 3.91e-07.
