We look at the division of 168370 by 45 
We're looking to find how many times 45 goes into 168370.

Moving on to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 45

On to step 2:
When dividing 16 by 45, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 45

On to step 3:
45 goes into 168 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 135 away from 168, we end up with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 45

Step 4:
If we divide 333 by 45, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 315 away from 333, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 45

Going ahead to step 5:
45 can be fit into 187 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Subtract 180 from 187 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 45

On to step 6:
When dividing 70 by 45, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 3741.0
Subtract 45 from 70 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 45, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 3741.5
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3741.55
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 3741.55 and a remainder of 0.025.
