We're dividing 53969793 by 659 
The aim is to understand the frequency of 659 in 53969793.

Advancing to step 1:
When dividing 5 by 659, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 659

Let's proceed to step 2:
The number 659 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 659

Moving on to step 3:
539 divided by 659 is 0 with a remainder of 539.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 539 after subtracting 0 from 539.
Fetch the next digit (6) from the dividend, attach it to 539 and continue: 5396 / 659

Step 4:
659 can be fit into 5396 8 times, resulting in a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5272 from 5396 leaves us with 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 659

Going ahead to step 5:
If we divide 1249 by 659, we get 1 and a remainder of 590.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 659 from 1249, we get 590.
Take the next digit (7) from the dividend and append it to 590, then repeat: 5907 / 659

Moving on to step 6:
659 can be fit into 5907 8 times, resulting in a remainder of 635.
Record the quotient 8 as the next digit in the result. 
Result so far: 818.0
If we subtract 5272 from 5907, we get 635.
Grab the next digit (9) from the dividend, add it to 635, then carry on: 6359 / 659

Going ahead to step 7:
If we divide 6359 by 659, we get 9 and a remainder of 428.
The next digit of our result is 9. 
Result so far: 8189.0
If we take 5931 away from 6359, we end up with 428.
Append the next digit (3) from the dividend to 428 and continue with: 4283 / 659

Let's proceed to step 8:
659 can be fit into 4283 6 times, resulting in a remainder of 329.
Write down 6 as next digit of the result. 
Result so far: 81896.0
Subtract 3954 from 4283 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 9:
659 goes into 3290 4 times with a remainder of 654.
Put 4 as the next digit of the answer. 
Result so far: 81896.4
Deduct 2636 from 3290 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Let's proceed to step 10:
6540 divided by 659 is 9 with a remainder of 609.
The number 9 becomes the next digit in our result. 
Result so far: 81896.49
Deduct 5931 from 6540 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Step 11:
6090 divided by 659 is 9 with a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 81896.499
If we subtract 5931 from 6090, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final outcome is 81896.499, with a leftover of 0.0159.
