We look at the division of 9945669 by 590 
The aim is to understand the frequency of 590 in 9945669.

Moving on to step 1:
The number 590 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 590

On to step 2:
If we divide 99 by 590, we get 0 and a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Append the next digit (4) from the dividend to 99 and continue with: 994 / 590

Step 3:
If we divide 994 by 590, we get 1 and a remainder of 404.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 404 after subtracting 590 from 994.
Fetch the next digit (5) from the dividend, attach it to 404 and continue: 4045 / 590

Step 4:
When dividing 4045 by 590, we get 6 with a remainder of 505.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 3540 from 4045 and we're left with 505.
Append the next digit (6) from the dividend to 505 and continue with: 5056 / 590

Step 5:
The number 590 fits into 5056 8 times, leaving a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Deduct 4720 from 5056 and we're left with 336.
Append the next digit (6) from the dividend to 336 and continue with: 3366 / 590

On to step 6:
When dividing 3366 by 590, we get 5 with a remainder of 416.
Write down 5 as next digit of the result. 
Result so far: 1685.0
Deduct 2950 from 3366 and we're left with 416.
Bring next digit (9) of the dividend behind the 416 and repeat the process: 4169 / 590

Going ahead to step 7:
590 goes into 4169 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 16857.0
If we take 4130 away from 4169, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 590, we get 0 and a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 16857.0
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 9:
When dividing 3900 by 590, we get 6 with a remainder of 360.
Write down 6 as next digit of the result. 
Result so far: 16857.06
If we take 3540 away from 3900, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
If we divide 3600 by 590, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 16857.066
If we take 3540 away from 3600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 16857.066 with a balance of 0.006.
