We're dividing 1683426 by 900 
We want to divide 1683426 by 900.

Advancing to step 1:
If we divide 1 by 900, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 900

Moving on to step 2:
If we divide 16 by 900, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 900

Step 3:
The number 900 fits into 168 0 times, leaving a remainder of 168.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 168 and we're left with 168.
Include the next digit (3) from the dividend after 168, then repeat: 1683 / 900

Moving on to step 4:
900 can be fit into 1683 1 times, resulting in a remainder of 783.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 900 from 1683 and we're left with 783.
Append the next digit (4) from the dividend to 783 and continue with: 7834 / 900

On to step 5:
900 can be fit into 7834 8 times, resulting in a remainder of 634.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 7200 from 7834 to get 634.
Fetch the next digit (2) from the dividend, attach it to 634 and continue: 6342 / 900

Step 6:
900 goes into 6342 7 times with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 187.0
If we subtract 6300 from 6342, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 900

Moving on to step 7:
When dividing 426 by 900, we get 0 with a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 1870.0
The remainder is 426 after subtracting 0 from 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 8:
4260 divided by 900 is 4 with a remainder of 660.
Record the quotient 4 as the next digit in the result. 
Result so far: 1870.4
Deduct 3600 from 4260 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 9:
The number 900 fits into 6600 7 times, leaving a remainder of 300.
Write down 7 as next digit of the result. 
Result so far: 1870.47
The remainder is 300 after subtracting 6300 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
The next digit of our result is 3. 
Result so far: 1870.473
Deduct 2700 from 3000 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
If we divide 3000 by 900, we get 3 and a remainder of 300.
The next digit of our result is 3. 
Result so far: 1870.4733
The remainder is 300 after subtracting 2700 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 1870.4733, with a leftover of 0.003.
