We divide 643231 by 60
We want to divide 643231 by 60.

Going ahead to step 1:
6 divided by 60 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 60

Advancing to step 2:
64 divided by 60 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 60 away from 64, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 60

On to step 3:
60 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 60

Going ahead to step 4:
If we divide 432 by 60, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 420 away from 432, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 60

Going ahead to step 5:
The number 60 fits into 123 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 1072.0
The remainder is 3 after subtracting 120 from 123.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 60

Let's proceed to step 6:
The number 60 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 10720.0
The remainder is 31 after subtracting 0 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 60, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10720.5
If we take 300 away from 310, we end up 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.

Moving on to step 8:
100 divided by 60 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 10720.51
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.

Let's proceed to step 9:
400 divided by 60 is 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 10720.516
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 10:
60 goes into 400 6 times with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 10720.5166
Subtracting 360 from 400 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.

The final outcome is 10720.5166, with a leftover of 0.0004.
