We look at the division of 53395957 by 659 
The aim is to understand the frequency of 659 in 53395957.

Step 1:
659 goes into 5 0 times with 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.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 659

Advancing to step 2:
659 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 659

On to step 3:
659 can be fit into 533 0 times, resulting in a remainder of 533.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 533 after subtracting 0 from 533.
Take the next digit (9) from the dividend and append it to 533, then repeat: 5339 / 659

On to step 4:
659 goes into 5339 8 times with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 5272 from 5339 and we're left with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 659

Step 5:
The number 659 fits into 675 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 659 from 675 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 659

Advancing to step 6:
169 divided by 659 is 0 with a remainder of 169.
Use 0 as the next digit of our solution. 
Result so far: 810.0
If we take 0 away from 169, we end up with 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 659

Moving on to step 7:
When dividing 1695 by 659, we get 2 with a remainder of 377.
Put 2 as the next digit of the answer. 
Result so far: 8102.0
If we take 1318 away from 1695, we end up with 377.
Take the next digit (7) from the dividend and append it to 377, then repeat: 3777 / 659

On to step 8:
659 can be fit into 3777 5 times, resulting in a remainder of 482.
Use 5 as the next digit of our solution. 
Result so far: 81025.0
Deduct 3295 from 3777 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 9:
659 can be fit into 4820 7 times, resulting in a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 81025.7
Deduct 4613 from 4820 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 10:
659 goes into 2070 3 times with a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 81025.73
The remainder is 93 after subtracting 1977 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 11:
659 goes into 930 1 times with a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 81025.731
Deduct 659 from 930 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 12:
If we divide 2710 by 659, we get 4 and a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 81025.7314
Deduct 2636 from 2710 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
If we divide 740 by 659, we get 1 and a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 81025.73141
Deduct 659 from 740 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 14:
If we divide 810 by 659, we get 1 and a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 81025.731411
If we take 659 away from 810, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 81025.731411, with a leftover of 1.51e-05.
