78598453 divided by 945 
The aim is to understand the frequency of 945 in 78598453.

Step 1:
945 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 945

Advancing to step 2:
The number 945 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 945

Let's proceed to step 3:
The number 945 fits into 785 0 times, leaving a remainder of 785.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 785, we get 785.
Grab the next digit (9) from the dividend, add it to 785, then carry on: 7859 / 945

On to step 4:
945 can be fit into 7859 8 times, resulting in a remainder of 299.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7560 from 7859 to get 299.
Include the next digit (8) from the dividend after 299, then repeat: 2998 / 945

On to step 5:
945 goes into 2998 3 times with a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2835 from 2998, we get 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 945

Let's proceed to step 6:
The number 945 fits into 1634 1 times, leaving a remainder of 689.
Use 1 as the next digit of our solution. 
Result so far: 831.0
The remainder is 689 after subtracting 945 from 1634.
Take the next digit (5) from the dividend and append it to 689, then repeat: 6895 / 945

Advancing to step 7:
If we divide 6895 by 945, we get 7 and a remainder of 280.
Write down 7 as next digit of the result. 
Result so far: 8317.0
If we subtract 6615 from 6895, we get 280.
Include the next digit (3) from the dividend after 280, then repeat: 2803 / 945

Step 8:
The number 945 fits into 2803 2 times, leaving a remainder of 913.
Use 2 as the next digit of our solution. 
Result so far: 83172.0
The remainder is 913 after subtracting 1890 from 2803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9130, and continue the process.

Step 9:
945 can be fit into 9130 9 times, resulting in a remainder of 625.
Record the quotient 9 as the next digit in the result. 
Result so far: 83172.9
If we take 8505 away from 9130, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 10:
The number 945 fits into 6250 6 times, leaving a remainder of 580.
Use 6 as the next digit of our solution. 
Result so far: 83172.96
Subtract 5670 from 6250 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 11:
If we divide 5800 by 945, we get 6 and a remainder of 130.
Record the quotient 6 as the next digit in the result. 
Result so far: 83172.966
Deduct 5670 from 5800 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 83172.966 with a balance of 0.013.
