661631 ÷ 59 
The aim is to understand the frequency of 59 in 661631.

Step 1:
If we divide 6 by 59, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 59

Advancing to step 2:
When dividing 66 by 59, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 59 from 66 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 59

Moving on to step 3:
71 divided by 59 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 59 from 71 leaves us with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 59

Advancing to step 4:
126 divided by 59 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 118 from 126 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 59

Let's proceed to step 5:
83 divided by 59 is 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1121.0
If we take 59 away from 83, we end up with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 59

Step 6:
59 goes into 241 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 11214.0
The remainder is 5 after subtracting 236 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 59 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11214.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
If we divide 500 by 59, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 11214.08
Subtract 472 from 500 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 59, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11214.084
The remainder is 44 after subtracting 236 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
59 goes into 440 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 11214.0847
The remainder is 27 after subtracting 413 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
The number 59 fits into 270 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 11214.08474
Subtract 236 from 270 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
59 goes into 340 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 11214.084745
If we take 295 away from 340, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
If we divide 450 by 59, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 11214.0847457
If we take 413 away from 450, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
If we divide 370 by 59, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 11214.08474576
Deduct 354 from 370 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 11214.08474576 with a remainder of 1.6e-08.
