Let's divide 124312 by 77
We want to figure out the number of times 124312 can be divided by 77.

Let's proceed to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 77

Advancing to step 2:
77 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 77

Let's proceed to step 3:
When dividing 124 by 77, we get 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 77 from 124 to get 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 77

Moving on to step 4:
77 goes into 473 6 times with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 462 from 473 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 77

Going ahead to step 5:
If we divide 111 by 77, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 161.0
If we subtract 77 from 111, we get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 77

Moving on to step 6:
342 divided by 77 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1614.0
Deduct 308 from 342 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
77 goes into 340 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1614.4
The remainder is 32 after subtracting 308 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 77 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1614.44
Deduct 308 from 320 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 1614.44 with a balance of 0.012.
