We're dividing 91819828 by 201 
The aim is to understand the frequency of 201 in 91819828.

On to step 1:
If we divide 9 by 201, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 201

Advancing to step 2:
201 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 201

Moving on to step 3:
When dividing 918 by 201, we get 4 with a remainder of 114.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 114 after subtracting 804 from 918.
Fetch the next digit (1) from the dividend, attach it to 114 and continue: 1141 / 201

Moving on to step 4:
201 can be fit into 1141 5 times, resulting in a remainder of 136.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 1005 from 1141 to get 136.
Include the next digit (9) from the dividend after 136, then repeat: 1369 / 201

Moving on to step 5:
1369 divided by 201 is 6 with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 456.0
If we take 1206 away from 1369, we end up with 163.
Bring next digit (8) of the dividend behind the 163 and repeat the process: 1638 / 201

Moving on to step 6:
201 goes into 1638 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 4568.0
If we subtract 1608 from 1638, we get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 201

Step 7:
201 can be fit into 302 1 times, resulting in a remainder of 101.
The next digit of our result is 1. 
Result so far: 45681.0
If we take 201 away from 302, we end up with 101.
Grab the next digit (8) from the dividend, add it to 101, then carry on: 1018 / 201

Going ahead to step 8:
When dividing 1018 by 201, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 456815.0
Subtracting 1005 from 1018 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 201, we get 0 and a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 456815.0
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
201 can be fit into 1300 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 456815.06
Deduct 1206 from 1300 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
201 can be fit into 940 4 times, resulting in a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 456815.064
If we subtract 804 from 940, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
1360 divided by 201 is 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 456815.0646
Subtracting 1206 from 1360 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
201 can be fit into 1540 7 times, resulting in a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 456815.06467
Subtracting 1407 from 1540 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 14:
When dividing 1330 by 201, we get 6 with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 456815.064676
Subtracting 1206 from 1330 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 15:
The number 201 fits into 1240 6 times, leaving a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 456815.0646766
If we take 1206 away from 1240, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 456815.0646766 with a remainder of 3.4e-07.
