We divide 210798 by 45
Let's see how many times 45 fits into 210798.

Let's proceed to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 45

Advancing to step 2:
The number 45 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 45

Advancing to step 3:
45 goes into 210 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 30 after subtracting 180 from 210.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 45

Step 4:
If we divide 307 by 45, we get 6 and a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 46.0
Deduct 270 from 307 and we're left with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 45

Advancing to step 5:
If we divide 379 by 45, we get 8 and a remainder of 19.
The next digit of our result is 8. 
Result so far: 468.0
Subtracting 360 from 379 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 45

Step 6:
If we divide 198 by 45, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4684.0
Deduct 180 from 198 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
45 can be fit into 180 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4684.4
Subtracting 180 from 180 leaves us 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.

Moving on to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4684.4
If we take 0 away from 0, we end up 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.

Going ahead to step 9:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4684.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4684.4, with a leftover of 0.0.
