We're dividing 898721 by 45 
Let's see how many times 45 fits into 898721.

Going ahead to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 45

Step 2:
The number 45 fits into 89 1 times, leaving a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 89, we get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 45

Going ahead to step 3:
448 divided by 45 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 405 away from 448, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 45

Going ahead to step 4:
The number 45 fits into 437 9 times, leaving a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Subtracting 405 from 437 leaves us with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 45

Moving on to step 5:
322 divided by 45 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 1997.0
If we subtract 315 from 322, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 45

Advancing to step 6:
45 can be fit into 71 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 19971.0
The remainder is 26 after subtracting 45 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
If we divide 260 by 45, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 19971.5
Deduct 225 from 260 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 45, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 19971.57
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 19971.577
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 19971.577, with a leftover of 0.0035.
