921440 divided by 1 
Let's see how many times 1 fits into 921440.

Advancing to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 9 from 9 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Moving on to step 2:
1 goes into 2 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 92.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 921.0
If we subtract 1 from 1, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Advancing to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 9214.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Going ahead to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 92144.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 921440.0
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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 921440.0
If we take 0 away from 0, we end up 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.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 921440.0
If we take 0 away from 0, we end up 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.

The final outcome is 921440.0, with a leftover of 0.0.
