Let's divide 39302053 by 57
The aim is to understand the frequency of 57 in 39302053.

On to step 1:
If we divide 3 by 57, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 57

Advancing to step 2:
57 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 57

Going ahead to step 3:
If we divide 393 by 57, we get 6 and a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 342 from 393 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 57

Moving on to step 4:
The number 57 fits into 510 8 times, leaving a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 456 from 510 leaves us with 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 57

Going ahead to step 5:
542 divided by 57 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 689.0
If we subtract 513 from 542, we get 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 57

Let's proceed to step 6:
57 goes into 290 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6895.0
The remainder is 5 after subtracting 285 from 290.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 57

On to step 7:
55 divided by 57 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 68950.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 57

Step 8:
The number 57 fits into 553 9 times, leaving a remainder of 40.
The next digit of our result is 9. 
Result so far: 689509.0
Subtracting 513 from 553 leaves us 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.

Going ahead to step 9:
When dividing 400 by 57, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 689509.7
Subtracting 399 from 400 leaves us with 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 10:
57 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 689509.7
Deduct 0 from 10 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 11:
57 can be fit into 100 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 689509.701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
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: 689509.7017
Subtracting 399 from 430 leaves us with 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 13:
When dividing 310 by 57, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 689509.70175
Subtracting 285 from 310 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 57, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 689509.701754
If we take 228 away from 250, we end up 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.

On to step 15:
When dividing 220 by 57, we get 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 689509.7017543
If we take 171 away from 220, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 16:
When dividing 490 by 57, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 689509.70175438
Subtract 456 from 490 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 689509.70175438 and a remainder of 3.4e-08.
