We're dividing 81625220 by 945 
The aim is to understand the frequency of 945 in 81625220.

Going ahead to step 1:
945 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 945

On to step 2:
When dividing 81 by 945, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 945

On to step 3:
945 goes into 816 0 times with a remainder of 816.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 816 after subtracting 0 from 816.
Take the next digit (2) from the dividend and append it to 816, then repeat: 8162 / 945

Moving on to step 4:
945 can be fit into 8162 8 times, resulting in a remainder of 602.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7560 from 8162, we get 602.
Include the next digit (5) from the dividend after 602, then repeat: 6025 / 945

Let's proceed to step 5:
When dividing 6025 by 945, we get 6 with a remainder of 355.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 5670 from 6025, we get 355.
Include the next digit (2) from the dividend after 355, then repeat: 3552 / 945

On to step 6:
945 goes into 3552 3 times with a remainder of 717.
Write down 3 as next digit of the result. 
Result so far: 863.0
If we subtract 2835 from 3552, we get 717.
Grab the next digit (2) from the dividend, add it to 717, then carry on: 7172 / 945

Advancing to step 7:
If we divide 7172 by 945, we get 7 and a remainder of 557.
The next digit of our result is 7. 
Result so far: 8637.0
If we subtract 6615 from 7172, we get 557.
Append the next digit (0) from the dividend to 557 and continue with: 5570 / 945

Step 8:
If we divide 5570 by 945, we get 5 and a remainder of 845.
Put 5 as the next digit of the answer. 
Result so far: 86375.0
If we take 4725 away from 5570, we end up with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Let's proceed to step 9:
8450 divided by 945 is 8 with a remainder of 890.
The number 8 becomes the next digit in our result. 
Result so far: 86375.8
The remainder is 890 after subtracting 7560 from 8450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 10:
The number 945 fits into 8900 9 times, leaving a remainder of 395.
Use 9 as the next digit of our solution. 
Result so far: 86375.89
The remainder is 395 after subtracting 8505 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 11:
3950 divided by 945 is 4 with a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 86375.894
If we subtract 3780 from 3950, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
The number 945 fits into 1700 1 times, leaving a remainder of 755.
Use 1 as the next digit of our solution. 
Result so far: 86375.8941
If we subtract 945 from 1700, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Let's proceed to step 13:
945 can be fit into 7550 7 times, resulting in a remainder of 935.
The next digit of our result is 7. 
Result so far: 86375.89417
If we take 6615 away from 7550, we end up with 935.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9350, and continue the process.

Moving on to step 14:
The number 945 fits into 9350 9 times, leaving a remainder of 845.
Write down 9 as next digit of the result. 
Result so far: 86375.894179
The remainder is 845 after subtracting 8505 from 9350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Going ahead to step 15:
945 can be fit into 8450 8 times, resulting in a remainder of 890.
The next digit of our result is 8. 
Result so far: 86375.8941798
If we take 7560 away from 8450, we end up with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Advancing to step 16:
If we divide 8900 by 945, we get 9 and a remainder of 395.
Use 9 as the next digit of our solution. 
Result so far: 86375.89417989
If we subtract 8505 from 8900, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

In conclusion, the division gives 86375.89417989 with a balance of 3.95e-07.
