We divide 421910 by 60
Our goal is to divide 421910 by 60.

Let's proceed to step 1:
The number 60 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 60

On to step 2:
If we divide 42 by 60, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 60

On to step 3:
60 goes into 421 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 1 after subtracting 420 from 421.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 60

On to step 4:
60 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 19, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 60

Going ahead to step 5:
If we divide 191 by 60, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 703.0
If we take 180 away from 191, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 60

Step 6:
If we divide 110 by 60, we get 1 and a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 7031.0
If we subtract 60 from 110, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
When dividing 500 by 60, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 7031.8
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 60 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 7031.83
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 60, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 7031.833
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7031.833, with a leftover of 0.002.
