We're dividing 857221 by 60 
Let's see how many times 60 fits into 857221.

Let's proceed to step 1:
60 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 60

On to step 2:
When dividing 85 by 60, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 60 from 85 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 60

On to step 3:
60 can be fit into 257 4 times, resulting in a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 240 from 257, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 60

Moving on to step 4:
When dividing 172 by 60, we get 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 120 from 172 to get 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 60

On to step 5:
The number 60 fits into 522 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 1428.0
Subtract 480 from 522 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 60

Going ahead to step 6:
When dividing 421 by 60, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 14287.0
Subtract 420 from 421 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
60 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14287.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 60, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 14287.01
Subtracting 60 from 100 leaves us 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:
400 divided by 60 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 14287.016
If we subtract 360 from 400, we 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.

Moving on to step 10:
60 goes into 400 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 14287.0166
If we take 360 away from 400, we end up 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.

Our division results in 14287.0166 with a remaining 0.0004.
