537486 ÷ 1 
Let's see how many times 1 fits into 537486.

Going ahead to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Moving on to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 53.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 3:
1 goes into 7 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 537.0
If we subtract 7 from 7, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 4:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 5374.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Step 5:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 53748.0
If we subtract 8 from 8, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

On to step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 537486.0
If we take 6 away from 6, 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.

Going ahead to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 537486.0
Subtract 0 from 0 to get 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.
The next digit of our result is 0. 
Result so far: 537486.0
Deduct 0 from 0 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.

The final outcome is 537486.0, with a leftover of 0.0.
