We're dividing 61638 by 1 
Our goal is to divide 61638 by 1.

Moving on to step 1:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Let's proceed to step 2:
1 goes into 1 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 616.0
Subtract 6 from 6 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 4:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 6163.0
If we subtract 3 from 3, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Advancing to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 61638.0
Deduct 8 from 8 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.

Advancing to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61638.0
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.

Let's proceed to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 61638.0
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.

The final outcome is 61638.0, with a leftover of 0.0.
