We're dividing 436989 by 63 
Let's see how many times 63 fits into 436989.

Advancing to step 1:
63 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 63

Step 2:
63 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 63

Going ahead to step 3:
63 goes into 436 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 378 away from 436, we end up with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 63

Step 4:
63 goes into 589 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 69.0
If we take 567 away from 589, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 63

Let's proceed to step 5:
228 divided by 63 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 693.0
Subtract 189 from 228 to get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 63

On to step 6:
399 divided by 63 is 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 6936.0
Subtract 378 from 399 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 63 fits into 210 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 6936.3
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 63, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 6936.33
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 6936.33 with a remainder of 0.021.
