We divide 8870431 by 450
Our goal is to divide 8870431 by 450.

Going ahead to step 1:
When dividing 8 by 450, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 450

Going ahead to step 2:
450 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Take the next digit (7) from the dividend and append it to 88, then repeat: 887 / 450

Let's proceed to step 3:
450 can be fit into 887 1 times, resulting in a remainder of 437.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 450 away from 887, we end up with 437.
Include the next digit (0) from the dividend after 437, then repeat: 4370 / 450

Going ahead to step 4:
4370 divided by 450 is 9 with a remainder of 320.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 4050 from 4370 leaves us with 320.
Fetch the next digit (4) from the dividend, attach it to 320 and continue: 3204 / 450

On to step 5:
If we divide 3204 by 450, we get 7 and a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 3150 from 3204 leaves us with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 450

Advancing to step 6:
The number 450 fits into 543 1 times, leaving a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 1971.0
Deduct 450 from 543 and we're left with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 450

Advancing to step 7:
450 can be fit into 931 2 times, resulting in a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 19712.0
The remainder is 31 after subtracting 900 from 931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
450 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 19712.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
450 goes into 3100 6 times with a remainder of 400.
The number 6 becomes the next digit in our result. 
Result so far: 19712.06
Deduct 2700 from 3100 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
450 can be fit into 4000 8 times, resulting in a remainder of 400.
The next digit of our result is 8. 
Result so far: 19712.068
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
When dividing 4000 by 450, we get 8 with a remainder of 400.
Write down 8 as next digit of the result. 
Result so far: 19712.0688
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 19712.0688, with a leftover of 0.004.
