147386 ÷ 45 
We're looking to find how many times 45 goes into 147386.

Step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 45

On to step 2:
If we divide 14 by 45, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 45

Going ahead to step 3:
45 can be fit into 147 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 12 after subtracting 135 from 147.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 45

Going ahead to step 4:
123 divided by 45 is 2 with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 90 from 123, we get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 45

On to step 5:
If we divide 338 by 45, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
Subtract 315 from 338 to get 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 45

Step 6:
The number 45 fits into 236 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 3275.0
The remainder is 11 after subtracting 225 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
45 goes into 110 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 3275.2
If we subtract 90 from 110, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3275.24
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3275.244
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3275.244 and a remainder of 0.002.
