We divide 12638607 by 60
We're looking to find how many times 60 goes into 12638607.

Moving on to step 1:
If we divide 1 by 60, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 60

Let's proceed to step 2:
60 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 60

On to step 3:
126 divided by 60 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 120 away from 126, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 60

Step 4:
60 goes into 63 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 60 from 63 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 60

Moving on to step 5:
38 divided by 60 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 38, we get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 60

Going ahead to step 6:
If we divide 386 by 60, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 2106.0
Subtract 360 from 386 to get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 60

On to step 7:
The number 60 fits into 260 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 21064.0
If we take 240 away from 260, we end up with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 60

Going ahead to step 8:
207 divided by 60 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 210643.0
If we subtract 180 from 207, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 60 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 210643.4
The remainder is 30 after subtracting 240 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
60 goes into 300 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 210643.45
Subtract 300 from 300 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.

On to step 11:
When dividing 0 by 60, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 210643.45
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.

Advancing to step 12:
60 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 210643.45
If we subtract 0 from 0, we 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.

The final result is 210643.45 with a remainder of 0.0.
