We're dividing 630870 by 57 
The aim is to understand the frequency of 57 in 630870.

Step 1:
When dividing 6 by 57, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 57

On to step 2:
If we divide 63 by 57, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 63 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 57

Let's proceed to step 3:
60 divided by 57 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 57 from 60 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 57

Step 4:
57 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 38, we get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 57

Step 5:
57 can be fit into 387 6 times, resulting in a remainder of 45.
The next digit of our result is 6. 
Result so far: 1106.0
If we subtract 342 from 387, we get 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 57

Going ahead to step 6:
When dividing 450 by 57, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 11067.0
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
When dividing 510 by 57, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 11067.8
Subtracting 456 from 510 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
When dividing 540 by 57, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 11067.89
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
57 goes into 270 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 11067.894
Subtracting 228 from 270 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
When dividing 420 by 57, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 11067.8947
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
If we divide 210 by 57, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 11067.89473
Subtracting 171 from 210 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
57 can be fit into 390 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 11067.894736
Deduct 342 from 390 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
When dividing 480 by 57, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 11067.8947368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
When dividing 240 by 57, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11067.89473684
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 11067.89473684, and the remainder is 1.2e-08.
