We divide 402037 by 1
Let's see how many times 1 fits into 402037.

Advancing to step 1:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 0, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Step 3:
2 divided by 1 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
If we subtract 2 from 2, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 4:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4020.0
Subtract 0 from 0 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 40203.0
If we take 3 away from 3, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 6:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 402037.0
Deduct 7 from 7 and we're left 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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 402037.0
Subtracting 0 from 0 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.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 402037.0
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.

Our division results in 402037.0 with a remaining 0.0.
