We look at the division of 55661938 by 266 
The aim is to understand the frequency of 266 in 55661938.

Going ahead to step 1:
The number 266 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 266

Let's proceed to step 2:
The number 266 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 266

Let's proceed to step 3:
556 divided by 266 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 532 from 556 and we're left with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 266

Moving on to step 4:
246 divided by 266 is 0 with a remainder of 246.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 246 after subtracting 0 from 246.
Fetch the next digit (1) from the dividend, attach it to 246 and continue: 2461 / 266

Moving on to step 5:
266 goes into 2461 9 times with a remainder of 67.
The next digit of our result is 9. 
Result so far: 209.0
Deduct 2394 from 2461 and we're left with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 266

Let's proceed to step 6:
When dividing 679 by 266, we get 2 with a remainder of 147.
Record the quotient 2 as the next digit in the result. 
Result so far: 2092.0
If we subtract 532 from 679, we get 147.
Include the next digit (3) from the dividend after 147, then repeat: 1473 / 266

On to step 7:
When dividing 1473 by 266, we get 5 with a remainder of 143.
The number 5 becomes the next digit in our result. 
Result so far: 20925.0
The remainder is 143 after subtracting 1330 from 1473.
Include the next digit (8) from the dividend after 143, then repeat: 1438 / 266

On to step 8:
266 can be fit into 1438 5 times, resulting in a remainder of 108.
The number 5 becomes the next digit in our result. 
Result so far: 209255.0
Subtracting 1330 from 1438 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
266 goes into 1080 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 209255.4
The remainder is 16 after subtracting 1064 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 266, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 209255.4
Subtracting 0 from 160 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.

Moving on to step 11:
266 can be fit into 1600 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 209255.406
If we take 1596 away from 1600, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
266 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 209255.406
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 266 is 1 with a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 209255.40601
Deduct 266 from 400 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 14:
266 goes into 1340 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 209255.406015
Subtracting 1330 from 1340 leaves us 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.

Advancing to step 15:
100 divided by 266 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 209255.406015
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
When dividing 1000 by 266, we get 3 with a remainder of 202.
Use 3 as the next digit of our solution. 
Result so far: 209255.40601503
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.

The quotient of the division is 209255.40601503, and the remainder is 2.02e-07.
