372854 ÷ 90 
We're looking to find how many times 90 goes into 372854.

Going ahead to step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 90

Step 2:
If we divide 37 by 90, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 90

On to step 3:
90 can be fit into 372 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 360 from 372, we get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 90

On to step 4:
128 divided by 90 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 90 from 128 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 90

Let's proceed to step 5:
90 can be fit into 385 4 times, resulting in a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 414.0
Deduct 360 from 385 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 90

On to step 6:
If we divide 254 by 90, we get 2 and a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 4142.0
If we subtract 180 from 254, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
When dividing 740 by 90, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 4142.8
If we subtract 720 from 740, 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.

Step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 4142.82
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.

On to step 9:
90 goes into 200 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 4142.822
Subtracting 180 from 200 leaves us 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.

Our division results in 4142.822 with a remaining 0.002.
