We're dividing 34087381 by 845 
The aim is to understand the frequency of 845 in 34087381.

Advancing to step 1:
If we divide 3 by 845, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 845

Advancing to step 2:
If we divide 34 by 845, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 845

Let's proceed to step 3:
If we divide 340 by 845, we get 0 and a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 340 to get 340.
Bring next digit (8) of the dividend behind the 340 and repeat the process: 3408 / 845

Going ahead to step 4:
If we divide 3408 by 845, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3380 away from 3408, we end up with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 845

Advancing to step 5:
The number 845 fits into 287 0 times, leaving a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 287, we get 287.
Fetch the next digit (3) from the dividend, attach it to 287 and continue: 2873 / 845

Moving on to step 6:
If we divide 2873 by 845, we get 3 and a remainder of 338.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
Subtracting 2535 from 2873 leaves us with 338.
Fetch the next digit (8) from the dividend, attach it to 338 and continue: 3388 / 845

Moving on to step 7:
If we divide 3388 by 845, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4034.0
If we take 3380 away from 3388, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 845

Moving on to step 8:
The number 845 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 40340.0
If we take 0 away from 81, we end up 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.

Moving on to step 9:
The number 845 fits into 810 0 times, leaving a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 40340.0
Subtracting 0 from 810 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 10:
845 goes into 8100 9 times with a remainder of 495.
Put 9 as the next digit of the answer. 
Result so far: 40340.09
If we take 7605 away from 8100, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 11:
4950 divided by 845 is 5 with a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 40340.095
If we take 4225 away from 4950, we end up with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Let's proceed to step 12:
845 goes into 7250 8 times with a remainder of 490.
The next digit of our result is 8. 
Result so far: 40340.0958
Subtracting 6760 from 7250 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 13:
845 goes into 4900 5 times with a remainder of 675.
The number 5 becomes the next digit in our result. 
Result so far: 40340.09585
Deduct 4225 from 4900 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 14:
If we divide 6750 by 845, we get 7 and a remainder of 835.
The number 7 becomes the next digit in our result. 
Result so far: 40340.095857
Subtracting 5915 from 6750 leaves us with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Step 15:
8350 divided by 845 is 9 with a remainder of 745.
The number 9 becomes the next digit in our result. 
Result so far: 40340.0958579
Subtracting 7605 from 8350 leaves us with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Let's proceed to step 16:
845 goes into 7450 8 times with a remainder of 690.
Record the quotient 8 as the next digit in the result. 
Result so far: 40340.09585798
Deduct 6760 from 7450 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The final result is 40340.09585798 with a remainder of 6.9e-07.
