501806 divided by 57 
The aim is to understand the frequency of 57 in 501806.

Let's proceed to step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 57

Going ahead to step 2:
The number 57 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 57

On to step 3:
The number 57 fits into 501 8 times, leaving a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 456 from 501, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 57

Moving on to step 4:
458 divided by 57 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 456 from 458 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 57

Advancing to step 5:
When dividing 20 by 57, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 880.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 57

On to step 6:
If we divide 206 by 57, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 8803.0
If we subtract 171 from 206, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
The number 57 fits into 350 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 8803.6
Subtracting 342 from 350 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
57 can be fit into 80 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 8803.61
Subtract 57 from 80 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
57 can be fit into 230 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 8803.614
If we subtract 228 from 230, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
57 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8803.614
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
57 goes into 200 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 8803.61403
If we subtract 171 from 200, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
When dividing 290 by 57, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8803.614035
If we take 285 away from 290, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
57 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8803.614035
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
If we divide 500 by 57, we get 8 and a remainder of 44.
The next digit of our result is 8. 
Result so far: 8803.61403508
Deduct 456 from 500 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 8803.61403508 and a remainder of 4.4e-08.
