354515 ÷ 89 
We want to figure out the number of times 354515 can be divided by 89.

Moving on to step 1:
89 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 89

On to step 2:
If we divide 35 by 89, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 89

On to step 3:
354 divided by 89 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 267 from 354 and we're left with 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 89

Moving on to step 4:
When dividing 875 by 89, we get 9 with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 801 from 875 and we're left with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 89

Let's proceed to step 5:
741 divided by 89 is 8 with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we subtract 712 from 741, we get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 89

Going ahead to step 6:
295 divided by 89 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 3983.0
If we take 267 away from 295, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
The number 89 fits into 280 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 3983.3
Deduct 267 from 280 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 89, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 3983.31
Subtract 89 from 130 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
When dividing 410 by 89, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 3983.314
Subtracting 356 from 410 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
89 goes into 540 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3983.3146
Subtract 534 from 540 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
If we divide 60 by 89, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3983.3146
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 89, we get 6 and a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 3983.314606
Subtracting 534 from 600 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
If we divide 660 by 89, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 3983.3146067
If we subtract 623 from 660, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
89 goes into 370 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3983.31460674
If we subtract 356 from 370, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 3983.31460674 with a balance of 1.4e-08.
