66406 divided by 57 
The aim is to understand the frequency of 57 in 66406.

Moving on to step 1:
57 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 57

Step 2:
When dividing 66 by 57, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 57 from 66 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 57

Going ahead to step 3:
When dividing 94 by 57, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 57 from 94 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 57

Going ahead to step 4:
When dividing 370 by 57, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 342 from 370 to get 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 57

Advancing to step 5:
57 goes into 286 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1165.0
Subtract 285 from 286 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
10 divided by 57 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1165.0
Subtracting 0 from 10 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 7:
The number 57 fits into 100 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1165.01
If we take 57 away from 100, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
When dividing 430 by 57, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 1165.017
Subtract 399 from 430 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
57 goes into 310 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1165.0175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 57, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 1165.01754
Subtracting 228 from 250 leaves us 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.

Let's proceed to step 11:
57 can be fit into 220 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 1165.017543
Subtract 171 from 220 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
490 divided by 57 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 1165.0175438
If we take 456 away from 490, 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.

Moving on to step 13:
340 divided by 57 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1165.01754385
Deduct 285 from 340 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 1165.01754385 with a remaining 5.5e-08.
