We're dividing 638602 by 60 
We're looking to find how many times 60 goes into 638602.

Step 1:
60 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 60

Let's proceed to step 2:
60 can be fit into 63 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 60 away from 63, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 60

Advancing to step 3:
60 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 60

On to step 4:
60 goes into 386 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 360 from 386 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 60

Moving on to step 5:
When dividing 260 by 60, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1064.0
If we subtract 240 from 260, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 60

On to step 6:
If we divide 202 by 60, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 10643.0
If we take 180 away from 202, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 60, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 10643.3
Subtract 180 from 220 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
60 goes into 400 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 10643.36
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 60, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 10643.366
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10643.366, with a leftover of 0.004.
