Let's divide 19963090 by 527
The aim is to understand the frequency of 527 in 19963090.

On to step 1:
If we divide 1 by 527, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 527

Let's proceed to step 2:
527 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 527

On to step 3:
527 goes into 199 0 times with a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Take the next digit (6) from the dividend and append it to 199, then repeat: 1996 / 527

Step 4:
1996 divided by 527 is 3 with a remainder of 415.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1581 from 1996 to get 415.
Grab the next digit (3) from the dividend, add it to 415, then carry on: 4153 / 527

Going ahead to step 5:
The number 527 fits into 4153 7 times, leaving a remainder of 464.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 3689 from 4153 leaves us with 464.
Include the next digit (0) from the dividend after 464, then repeat: 4640 / 527

Advancing to step 6:
527 can be fit into 4640 8 times, resulting in a remainder of 424.
Use 8 as the next digit of our solution. 
Result so far: 378.0
The remainder is 424 after subtracting 4216 from 4640.
Grab the next digit (9) from the dividend, add it to 424, then carry on: 4249 / 527

Step 7:
The number 527 fits into 4249 8 times, leaving a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 3788.0
The remainder is 33 after subtracting 4216 from 4249.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 527

Step 8:
527 goes into 330 0 times with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 37880.0
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 9:
3300 divided by 527 is 6 with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 37880.6
If we subtract 3162 from 3300, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 10:
When dividing 1380 by 527, we get 2 with a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 37880.62
The remainder is 326 after subtracting 1054 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 11:
3260 divided by 527 is 6 with a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 37880.626
If we take 3162 away from 3260, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 12:
If we divide 980 by 527, we get 1 and a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 37880.6261
Subtract 527 from 980 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 13:
527 goes into 4530 8 times with a remainder of 314.
Use 8 as the next digit of our solution. 
Result so far: 37880.62618
Subtracting 4216 from 4530 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 14:
527 can be fit into 3140 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 37880.626185
Subtract 2635 from 3140 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 15:
5050 divided by 527 is 9 with a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 37880.6261859
Subtracting 4743 from 5050 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 16:
527 goes into 3070 5 times with a remainder of 435.
The next digit of our result is 5. 
Result so far: 37880.62618595
The remainder is 435 after subtracting 2635 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Our division results in 37880.62618595 with a remaining 4.35e-07.
