We look at the division of 770370 by 60 
Let's see how many times 60 fits into 770370.

Going ahead to step 1:
60 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 60

Going ahead to step 2:
If we divide 77 by 60, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 60 from 77 to get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 60

On to step 3:
If we divide 170 by 60, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 120 from 170 and we're left with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 60

Moving on to step 4:
503 divided by 60 is 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 480 from 503 and we're left with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 60

Moving on to step 5:
237 divided by 60 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 1283.0
If we take 180 away from 237, we end up with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 60

Going ahead to step 6:
The number 60 fits into 570 9 times, leaving a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 12839.0
Subtracting 540 from 570 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
60 goes into 300 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12839.5
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 60 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12839.5
Subtract 0 from 0 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 9:
60 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12839.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 12839.5 with a balance of 0.0.
