We're dividing 187450 by 46 
We want to figure out the number of times 187450 can be divided by 46.

Step 1:
46 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 46

Step 2:
46 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 46

On to step 3:
When dividing 187 by 46, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 184 from 187, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 46

Step 4:
If we divide 34 by 46, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 34, we get 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 46

On to step 5:
46 can be fit into 345 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
Deduct 322 from 345 and we're left with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 46

Let's proceed to step 6:
When dividing 230 by 46, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4075.0
If we subtract 230 from 230, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
46 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4075.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 46, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4075.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4075.0 with a remaining 0.0.
