151415 divided by 45 
Let's see how many times 45 fits into 151415.

Moving on to step 1:
45 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 45

Moving on to step 2:
If we divide 15 by 45, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 45

Going ahead to step 3:
The number 45 fits into 151 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 16 after subtracting 135 from 151.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 45

Step 4:
45 goes into 164 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 135 away from 164, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 45

Step 5:
When dividing 291 by 45, we get 6 with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 336.0
The remainder is 21 after subtracting 270 from 291.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 45

Advancing to step 6:
When dividing 215 by 45, we get 4 with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 3364.0
If we take 180 away from 215, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
If we divide 350 by 45, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 3364.7
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 3364.77
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 3364.77 with a remainder of 0.035.
