Let's divide 20017755 by 845
The aim is to understand the frequency of 845 in 20017755.

Step 1:
If we divide 2 by 845, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 845

Step 2:
845 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 845

Advancing to step 3:
If we divide 200 by 845, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 200 leaves us with 200.
Take the next digit (1) from the dividend and append it to 200, then repeat: 2001 / 845

Advancing to step 4:
When dividing 2001 by 845, we get 2 with a remainder of 311.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 311 after subtracting 1690 from 2001.
Take the next digit (7) from the dividend and append it to 311, then repeat: 3117 / 845

On to step 5:
The number 845 fits into 3117 3 times, leaving a remainder of 582.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 2535 from 3117 to get 582.
Fetch the next digit (7) from the dividend, attach it to 582 and continue: 5827 / 845

Going ahead to step 6:
5827 divided by 845 is 6 with a remainder of 757.
Put 6 as the next digit of the answer. 
Result so far: 236.0
Subtracting 5070 from 5827 leaves us with 757.
Append the next digit (5) from the dividend to 757 and continue with: 7575 / 845

Step 7:
When dividing 7575 by 845, we get 8 with a remainder of 815.
Record the quotient 8 as the next digit in the result. 
Result so far: 2368.0
Deduct 6760 from 7575 and we're left with 815.
Bring next digit (5) of the dividend behind the 815 and repeat the process: 8155 / 845

Moving on to step 8:
When dividing 8155 by 845, we get 9 with a remainder of 550.
Write down 9 as next digit of the result. 
Result so far: 23689.0
If we subtract 7605 from 8155, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 9:
If we divide 5500 by 845, we get 6 and a remainder of 430.
Write down 6 as next digit of the result. 
Result so far: 23689.6
Subtracting 5070 from 5500 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
The number 845 fits into 4300 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 23689.65
If we subtract 4225 from 4300, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
When dividing 750 by 845, we get 0 with a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 23689.65
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 12:
845 goes into 7500 8 times with a remainder of 740.
Put 8 as the next digit of the answer. 
Result so far: 23689.6508
Subtract 6760 from 7500 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 13:
When dividing 7400 by 845, we get 8 with a remainder of 640.
Use 8 as the next digit of our solution. 
Result so far: 23689.65088
Subtract 6760 from 7400 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 23689.65088 with a remaining 0.00064.
