We're dividing 70349 by 45 
We want to figure out the number of times 70349 can be divided by 45.

Step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 45

Advancing to step 2:
When dividing 70 by 45, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 70, we end up with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 45

On to step 3:
If we divide 253 by 45, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 225 from 253 and we're left with 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 45

Going ahead to step 4:
45 goes into 284 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 270 from 284 to get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 45

Moving on to step 5:
149 divided by 45 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 1563.0
Subtract 135 from 149 to 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.

Advancing to step 6:
When dividing 140 by 45, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1563.3
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 45 fits into 50 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1563.31
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1563.311
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 1563.311 with a remaining 0.0005.
