63903527 divided by 691 
The aim is to understand the frequency of 691 in 63903527.

Advancing to step 1:
691 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 691

Advancing to step 2:
691 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 691

Going ahead to step 3:
691 goes into 639 0 times with a remainder of 639.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 639, we get 639.
Grab the next digit (0) from the dividend, add it to 639, then carry on: 6390 / 691

Moving on to step 4:
The number 691 fits into 6390 9 times, leaving a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 6219 from 6390, we get 171.
Bring next digit (3) of the dividend behind the 171 and repeat the process: 1713 / 691

On to step 5:
1713 divided by 691 is 2 with a remainder of 331.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we take 1382 away from 1713, we end up with 331.
Include the next digit (5) from the dividend after 331, then repeat: 3315 / 691

Advancing to step 6:
691 can be fit into 3315 4 times, resulting in a remainder of 551.
Write down 4 as next digit of the result. 
Result so far: 924.0
Subtract 2764 from 3315 to get 551.
Append the next digit (2) from the dividend to 551 and continue with: 5512 / 691

Let's proceed to step 7:
The number 691 fits into 5512 7 times, leaving a remainder of 675.
The next digit of our result is 7. 
Result so far: 9247.0
Subtracting 4837 from 5512 leaves us with 675.
Bring next digit (7) of the dividend behind the 675 and repeat the process: 6757 / 691

Let's proceed to step 8:
If we divide 6757 by 691, we get 9 and a remainder of 538.
Put 9 as the next digit of the answer. 
Result so far: 92479.0
Subtract 6219 from 6757 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 9:
5380 divided by 691 is 7 with a remainder of 543.
Put 7 as the next digit of the answer. 
Result so far: 92479.7
Subtracting 4837 from 5380 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 10:
If we divide 5430 by 691, we get 7 and a remainder of 593.
Use 7 as the next digit of our solution. 
Result so far: 92479.77
Subtract 4837 from 5430 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Our division results in 92479.77 with a remaining 0.593.
