We're dividing 551673 by 57 
The aim is to understand the frequency of 57 in 551673.

Going ahead to step 1:
The number 57 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 57

Let's proceed to step 2:
55 divided by 57 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 57

Moving on to step 3:
551 divided by 57 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 513 from 551, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 57

Advancing to step 4:
The number 57 fits into 386 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 44 after subtracting 342 from 386.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 57

Going ahead to step 5:
If we divide 447 by 57, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 967.0
Deduct 399 from 447 and we're left with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 57

On to step 6:
When dividing 483 by 57, we get 8 with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 9678.0
If we take 456 away from 483, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
The number 57 fits into 270 4 times, leaving a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 9678.4
If we take 228 away from 270, we end up 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.

Let's proceed to step 8:
420 divided by 57 is 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 9678.47
The remainder is 21 after subtracting 399 from 420.
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 9:
57 goes into 210 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 9678.473
Subtract 171 from 210 to 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.

Advancing to step 10:
57 can be fit into 390 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 9678.4736
If we take 342 away from 390, we end up 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.

Going ahead to step 11:
The number 57 fits into 480 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 9678.47368
Deduct 456 from 480 and we're left 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.

Going ahead to step 12:
240 divided by 57 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 9678.473684
Subtract 228 from 240 to get 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 13:
When dividing 120 by 57, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9678.4736842
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 57 fits into 60 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 9678.47368421
Subtract 57 from 60 to 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.

The quotient of the division is 9678.47368421, and the remainder is 3e-09.
