400638 divided by 60 
Our goal is to divide 400638 by 60.

Advancing to step 1:
60 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 60

Let's proceed to step 2:
60 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 60

On to step 3:
400 divided by 60 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 360 from 400 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 60

Advancing to step 4:
If we divide 406 by 60, we get 6 and a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 360 from 406 leaves us with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 60

Moving on to step 5:
If we divide 463 by 60, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 667.0
If we subtract 420 from 463, we get 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 60

Let's proceed to step 6:
If we divide 438 by 60, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 6677.0
Subtracting 420 from 438 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
60 goes into 180 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 6677.3
Deduct 180 from 180 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.

Step 8:
If we divide 0 by 60, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6677.3
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.

Moving on to step 9:
The number 60 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6677.3
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.

The final outcome is 6677.3, with a leftover of 0.0.
