99305142 ÷ 266 
The aim is to understand the frequency of 266 in 99305142.

On to step 1:
266 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 266

Let's proceed to step 2:
If we divide 99 by 266, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 266

Let's proceed to step 3:
266 can be fit into 993 3 times, resulting in a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 798 from 993 to get 195.
Take the next digit (0) from the dividend and append it to 195, then repeat: 1950 / 266

On to step 4:
If we divide 1950 by 266, we get 7 and a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 1862 from 1950 to get 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 266

Advancing to step 5:
If we divide 885 by 266, we get 3 and a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 373.0
If we subtract 798 from 885, we get 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 266

Going ahead to step 6:
871 divided by 266 is 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 3733.0
Subtract 798 from 871 to get 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 266

Going ahead to step 7:
266 goes into 734 2 times with a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 37332.0
Subtracting 532 from 734 leaves us with 202.
Fetch the next digit (2) from the dividend, attach it to 202 and continue: 2022 / 266

On to step 8:
When dividing 2022 by 266, we get 7 with a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 373327.0
Subtracting 1862 from 2022 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
266 can be fit into 1600 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 373327.6
Subtract 1596 from 1600 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 266, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 373327.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 266, we get 1 with a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 373327.601
The remainder is 134 after subtracting 266 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 12:
266 can be fit into 1340 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 373327.6015
Deduct 1330 from 1340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
266 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 373327.6015
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
266 can be fit into 1000 3 times, resulting in a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 373327.601503
Subtracting 798 from 1000 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 15:
If we divide 2020 by 266, we get 7 and a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 373327.6015037
Subtracting 1862 from 2020 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 16:
266 can be fit into 1580 5 times, resulting in a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 373327.60150375
If we take 1330 away from 1580, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 373327.60150375, with a leftover of 2.5e-07.
