We look at the division of 769026 by 57 
The aim is to understand the frequency of 57 in 769026.

Advancing to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 57

Step 2:
57 goes into 76 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 57 from 76 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 57

Going ahead to step 3:
199 divided by 57 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 28 after subtracting 171 from 199.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 57

Advancing to step 4:
The number 57 fits into 280 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
Subtract 228 from 280 to get 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 57

On to step 5:
522 divided by 57 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1349.0
Deduct 513 from 522 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 57

Going ahead to step 6:
57 goes into 96 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 13491.0
If we subtract 57 from 96, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
57 can be fit into 390 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 13491.6
The remainder is 48 after subtracting 342 from 390.
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 8:
When dividing 480 by 57, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 13491.68
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
57 can be fit into 240 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 13491.684
Deduct 228 from 240 and we're left 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.

Going ahead to step 10:
57 goes into 120 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 13491.6842
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
If we divide 60 by 57, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 13491.68421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
30 divided by 57 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13491.68421
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
When dividing 300 by 57, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13491.6842105
If we take 285 away from 300, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
The number 57 fits into 150 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 13491.68421052
Subtracting 114 from 150 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 13491.68421052, and the remainder is 3.6e-08.
