89891595 divided by 266 
The aim is to understand the frequency of 266 in 89891595.

Going ahead to step 1:
The number 266 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 266

Moving on to step 2:
89 divided by 266 is 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 266

On to step 3:
266 goes into 898 3 times with a remainder of 100.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 798 from 898, we get 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 266

On to step 4:
1009 divided by 266 is 3 with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 798 from 1009 leaves us with 211.
Grab the next digit (1) from the dividend, add it to 211, then carry on: 2111 / 266

Advancing to step 5:
When dividing 2111 by 266, we get 7 with a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 337.0
Subtracting 1862 from 2111 leaves us with 249.
Grab the next digit (5) from the dividend, add it to 249, then carry on: 2495 / 266

Moving on to step 6:
2495 divided by 266 is 9 with a remainder of 101.
The next digit of our result is 9. 
Result so far: 3379.0
Deduct 2394 from 2495 and we're left with 101.
Fetch the next digit (9) from the dividend, attach it to 101 and continue: 1019 / 266

Step 7:
The number 266 fits into 1019 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 33793.0
The remainder is 221 after subtracting 798 from 1019.
Take the next digit (5) from the dividend and append it to 221, then repeat: 2215 / 266

Going ahead to step 8:
266 can be fit into 2215 8 times, resulting in a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 337938.0
If we take 2128 away from 2215, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
When dividing 870 by 266, we get 3 with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 337938.3
The remainder is 72 after subtracting 798 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 266, we get 2 and a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 337938.32
The remainder is 188 after subtracting 532 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 11:
266 can be fit into 1880 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 337938.327
The remainder is 18 after subtracting 1862 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
180 divided by 266 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 337938.327
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
1800 divided by 266 is 6 with a remainder of 204.
Write down 6 as next digit of the result. 
Result so far: 337938.32706
Deduct 1596 from 1800 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 14:
When dividing 2040 by 266, we get 7 with a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 337938.327067
The remainder is 178 after subtracting 1862 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 15:
If we divide 1780 by 266, we get 6 and a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 337938.3270676
Subtracting 1596 from 1780 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
If we divide 1840 by 266, we get 6 and a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 337938.32706766
If we subtract 1596 from 1840, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 337938.32706766 with a remainder of 2.44e-07.
