90166156 ÷ 981 
The aim is to understand the frequency of 981 in 90166156.

Moving on to step 1:
The number 981 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 981

Advancing to step 2:
90 divided by 981 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 981

On to step 3:
901 divided by 981 is 0 with a remainder of 901.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 901, we get 901.
Take the next digit (6) from the dividend and append it to 901, then repeat: 9016 / 981

Step 4:
When dividing 9016 by 981, we get 9 with a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 8829 from 9016 to get 187.
Take the next digit (6) from the dividend and append it to 187, then repeat: 1876 / 981

Moving on to step 5:
The number 981 fits into 1876 1 times, leaving a remainder of 895.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 981 from 1876 leaves us with 895.
Fetch the next digit (1) from the dividend, attach it to 895 and continue: 8951 / 981

Step 6:
981 goes into 8951 9 times with a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 919.0
If we subtract 8829 from 8951, we get 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 981

Moving on to step 7:
981 can be fit into 1225 1 times, resulting in a remainder of 244.
Record the quotient 1 as the next digit in the result. 
Result so far: 9191.0
The remainder is 244 after subtracting 981 from 1225.
Fetch the next digit (6) from the dividend, attach it to 244 and continue: 2446 / 981

Going ahead to step 8:
981 goes into 2446 2 times with a remainder of 484.
Put 2 as the next digit of the answer. 
Result so far: 91912.0
If we subtract 1962 from 2446, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 9:
981 goes into 4840 4 times with a remainder of 916.
The next digit of our result is 4. 
Result so far: 91912.4
Subtracting 3924 from 4840 leaves us with 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

Let's proceed to step 10:
981 goes into 9160 9 times with a remainder of 331.
The next digit of our result is 9. 
Result so far: 91912.49
If we take 8829 away from 9160, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 11:
When dividing 3310 by 981, we get 3 with a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 91912.493
If we subtract 2943 from 3310, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 12:
981 goes into 3670 3 times with a remainder of 727.
Use 3 as the next digit of our solution. 
Result so far: 91912.4933
Subtract 2943 from 3670 to get 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

The quotient of the division is 91912.4933, and the remainder is 0.00727.
