93188101 ÷ 981 
The aim is to understand the frequency of 981 in 93188101.

On to step 1:
When dividing 9 by 981, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 981

Going ahead to step 2:
When dividing 93 by 981, we get 0 with a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 93, we end up with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 981

On to step 3:
When dividing 931 by 981, we get 0 with a remainder of 931.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 931 to get 931.
Fetch the next digit (8) from the dividend, attach it to 931 and continue: 9318 / 981

Going ahead to step 4:
If we divide 9318 by 981, we get 9 and a remainder of 489.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 8829 from 9318, we get 489.
Include the next digit (8) from the dividend after 489, then repeat: 4898 / 981

Going ahead to step 5:
981 goes into 4898 4 times with a remainder of 974.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 3924 from 4898 and we're left with 974.
Bring next digit (1) of the dividend behind the 974 and repeat the process: 9741 / 981

On to step 6:
The number 981 fits into 9741 9 times, leaving a remainder of 912.
Put 9 as the next digit of the answer. 
Result so far: 949.0
If we take 8829 away from 9741, we end up with 912.
Append the next digit (0) from the dividend to 912 and continue with: 9120 / 981

Step 7:
When dividing 9120 by 981, we get 9 with a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 9499.0
Deduct 8829 from 9120 and we're left with 291.
Append the next digit (1) from the dividend to 291 and continue with: 2911 / 981

On to step 8:
The number 981 fits into 2911 2 times, leaving a remainder of 949.
Put 2 as the next digit of the answer. 
Result so far: 94992.0
If we subtract 1962 from 2911, we get 949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Let's proceed to step 9:
981 goes into 9490 9 times with a remainder of 661.
The number 9 becomes the next digit in our result. 
Result so far: 94992.9
Subtracting 8829 from 9490 leaves us with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

On to step 10:
981 can be fit into 6610 6 times, resulting in a remainder of 724.
Put 6 as the next digit of the answer. 
Result so far: 94992.96
If we take 5886 away from 6610, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 11:
7240 divided by 981 is 7 with a remainder of 373.
Record the quotient 7 as the next digit in the result. 
Result so far: 94992.967
If we take 6867 away from 7240, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 12:
981 goes into 3730 3 times with a remainder of 787.
Use 3 as the next digit of our solution. 
Result so far: 94992.9673
Deduct 2943 from 3730 and we're left with 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Step 13:
The number 981 fits into 7870 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 94992.96738
If we take 7848 away from 7870, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
If we divide 220 by 981, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 94992.96738
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
The number 981 fits into 2200 2 times, leaving a remainder of 238.
Use 2 as the next digit of our solution. 
Result so far: 94992.9673802
Deduct 1962 from 2200 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 16:
If we divide 2380 by 981, we get 2 and a remainder of 418.
Use 2 as the next digit of our solution. 
Result so far: 94992.96738022
If we take 1962 away from 2380, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

After the division, we end up with 94992.96738022 and a remainder of 4.18e-07.
