We're dividing 777021 by 57 
The aim is to understand the frequency of 57 in 777021.

Let's proceed to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 57

Moving on to step 2:
The number 57 fits into 77 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 57 from 77 to get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 57

Let's proceed to step 3:
The number 57 fits into 207 3 times, leaving a remainder of 36.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 171 from 207 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 57

On to step 4:
57 goes into 360 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 136.0
If we take 342 away from 360, we end up with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 57

Going ahead to step 5:
If we divide 182 by 57, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1363.0
If we subtract 171 from 182, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 57

Step 6:
The number 57 fits into 111 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 13631.0
Subtract 57 from 111 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
The number 57 fits into 540 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 13631.9
If we subtract 513 from 540, we 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.

Step 8:
When dividing 270 by 57, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 13631.94
If we subtract 228 from 270, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
57 goes into 420 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 13631.947
Subtract 399 from 420 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
The number 57 fits into 210 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 13631.9473
The remainder is 39 after subtracting 171 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
When dividing 390 by 57, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 13631.94736
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
57 goes into 480 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13631.947368
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 57, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 13631.9473684
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.

Let's proceed to step 14:
57 goes into 120 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 13631.94736842
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 13631.94736842, and the remainder is 6e-09.
