We look at the division of 85966907 by 945 
The aim is to understand the frequency of 945 in 85966907.

Moving on to step 1:
8 divided by 945 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 945

On to step 2:
If we divide 85 by 945, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 945

On to step 3:
945 goes into 859 0 times with a remainder of 859.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 859 after subtracting 0 from 859.
Grab the next digit (6) from the dividend, add it to 859, then carry on: 8596 / 945

Going ahead to step 4:
945 goes into 8596 9 times with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 91 after subtracting 8505 from 8596.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 945

Going ahead to step 5:
The number 945 fits into 916 0 times, leaving a remainder of 916.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 916, we end up with 916.
Fetch the next digit (9) from the dividend, attach it to 916 and continue: 9169 / 945

Step 6:
The number 945 fits into 9169 9 times, leaving a remainder of 664.
Put 9 as the next digit of the answer. 
Result so far: 909.0
Subtract 8505 from 9169 to get 664.
Take the next digit (0) from the dividend and append it to 664, then repeat: 6640 / 945

Moving on to step 7:
945 can be fit into 6640 7 times, resulting in a remainder of 25.
The next digit of our result is 7. 
Result so far: 9097.0
Subtract 6615 from 6640 to get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 945

Let's proceed to step 8:
945 goes into 257 0 times with a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 90970.0
If we subtract 0 from 257, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 9:
945 goes into 2570 2 times with a remainder of 680.
Use 2 as the next digit of our solution. 
Result so far: 90970.2
Subtracting 1890 from 2570 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 10:
945 can be fit into 6800 7 times, resulting in a remainder of 185.
The next digit of our result is 7. 
Result so far: 90970.27
If we take 6615 away from 6800, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
1850 divided by 945 is 1 with a remainder of 905.
Record the quotient 1 as the next digit in the result. 
Result so far: 90970.271
If we take 945 away from 1850, we end up with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Step 12:
945 goes into 9050 9 times with a remainder of 545.
Record the quotient 9 as the next digit in the result. 
Result so far: 90970.2719
The remainder is 545 after subtracting 8505 from 9050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 13:
5450 divided by 945 is 5 with a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 90970.27195
Subtracting 4725 from 5450 leaves us 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.

On to step 14:
7250 divided by 945 is 7 with a remainder of 635.
The number 7 becomes the next digit in our result. 
Result so far: 90970.271957
If we subtract 6615 from 7250, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 15:
6350 divided by 945 is 6 with a remainder of 680.
The next digit of our result is 6. 
Result so far: 90970.2719576
Subtracting 5670 from 6350 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 16:
When dividing 6800 by 945, we get 7 with a remainder of 185.
The next digit of our result is 7. 
Result so far: 90970.27195767
If we take 6615 away from 6800, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The quotient of the division is 90970.27195767, and the remainder is 1.85e-07.
