358591 divided by 45 
The aim is to understand the frequency of 45 in 358591.

Step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 45

Moving on to step 2:
35 divided by 45 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 45

Moving on to step 3:
If we divide 358 by 45, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 43 after subtracting 315 from 358.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 45

On to step 4:
If we divide 435 by 45, we get 9 and a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we subtract 405 from 435, we get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 45

On to step 5:
309 divided by 45 is 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Deduct 270 from 309 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 45

Going ahead to step 6:
45 goes into 391 8 times with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 7968.0
Subtract 360 from 391 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 45, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 7968.6
If we subtract 270 from 310, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 7968.68
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 7968.688
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 7968.688 with a balance of 0.004.
