52140686 ÷ 627 
The aim is to understand the frequency of 627 in 52140686.

Advancing to step 1:
If we divide 5 by 627, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 627

Advancing to step 2:
52 divided by 627 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 627

Let's proceed to step 3:
627 can be fit into 521 0 times, resulting in a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 521, we get 521.
Grab the next digit (4) from the dividend, add it to 521, then carry on: 5214 / 627

Let's proceed to step 4:
627 can be fit into 5214 8 times, resulting in a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5016 from 5214 and we're left with 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 627

Moving on to step 5:
If we divide 1980 by 627, we get 3 and a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 99 after subtracting 1881 from 1980.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 627

Going ahead to step 6:
627 goes into 996 1 times with a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 831.0
Deduct 627 from 996 and we're left with 369.
Grab the next digit (8) from the dividend, add it to 369, then carry on: 3698 / 627

Advancing to step 7:
The number 627 fits into 3698 5 times, leaving a remainder of 563.
Use 5 as the next digit of our solution. 
Result so far: 8315.0
Subtracting 3135 from 3698 leaves us with 563.
Bring next digit (6) of the dividend behind the 563 and repeat the process: 5636 / 627

Moving on to step 8:
627 can be fit into 5636 8 times, resulting in a remainder of 620.
Put 8 as the next digit of the answer. 
Result so far: 83158.0
If we subtract 5016 from 5636, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 9:
If we divide 6200 by 627, we get 9 and a remainder of 557.
The number 9 becomes the next digit in our result. 
Result so far: 83158.9
Deduct 5643 from 6200 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Advancing to step 10:
When dividing 5570 by 627, we get 8 with a remainder of 554.
Use 8 as the next digit of our solution. 
Result so far: 83158.98
If we subtract 5016 from 5570, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 11:
627 goes into 5540 8 times with a remainder of 524.
The number 8 becomes the next digit in our result. 
Result so far: 83158.988
The remainder is 524 after subtracting 5016 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

After the division, we end up with 83158.988 and a remainder of 0.0524.
