We're dividing 672070 by 57 
The aim is to understand the frequency of 57 in 672070.

Let's proceed to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 57

Advancing to step 2:
If we divide 67 by 57, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 57 from 67, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 57

Let's proceed to step 3:
The number 57 fits into 102 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 45 after subtracting 57 from 102.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 57

Going ahead to step 4:
450 divided by 57 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 399 from 450 to get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 57

Moving on to step 5:
57 goes into 517 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1179.0
If we take 513 away from 517, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 57

Advancing to step 6:
If we divide 40 by 57, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11790.0
Subtracting 0 from 40 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.

Step 7:
57 goes into 400 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 11790.7
Deduct 399 from 400 and we're left 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.

Going ahead to step 8:
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: 11790.7
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.

Let's proceed to step 9:
57 can be fit into 100 1 times, resulting in a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 11790.701
Subtract 57 from 100 to 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.

Let's proceed to step 10:
57 can be fit into 430 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 11790.7017
If we subtract 399 from 430, we 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 11:
310 divided by 57 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11790.70175
Deduct 285 from 310 and we're left 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.

Step 12:
250 divided by 57 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 11790.701754
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
If we divide 220 by 57, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 11790.7017543
If we subtract 171 from 220, we 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.

Let's proceed to step 14:
57 can be fit into 490 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 11790.70175438
Subtracting 456 from 490 leaves us 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.

The final result is 11790.70175438 with a remainder of 3.4e-08.
