We look at the division of 77439407 by 834 
Our goal is to divide 77439407 by 834.

On to step 1:
834 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 834

Advancing to step 2:
The number 834 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 834

Let's proceed to step 3:
When dividing 774 by 834, we get 0 with a remainder of 774.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 774 to get 774.
Fetch the next digit (3) from the dividend, attach it to 774 and continue: 7743 / 834

Step 4:
If we divide 7743 by 834, we get 9 and a remainder of 237.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7506 from 7743 to get 237.
Grab the next digit (9) from the dividend, add it to 237, then carry on: 2379 / 834

Moving on to step 5:
If we divide 2379 by 834, we get 2 and a remainder of 711.
The next digit of our result is 2. 
Result so far: 92.0
If we take 1668 away from 2379, we end up with 711.
Fetch the next digit (4) from the dividend, attach it to 711 and continue: 7114 / 834

Advancing to step 6:
The number 834 fits into 7114 8 times, leaving a remainder of 442.
The next digit of our result is 8. 
Result so far: 928.0
The remainder is 442 after subtracting 6672 from 7114.
Grab the next digit (0) from the dividend, add it to 442, then carry on: 4420 / 834

Advancing to step 7:
When dividing 4420 by 834, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 9285.0
Deduct 4170 from 4420 and we're left with 250.
Fetch the next digit (7) from the dividend, attach it to 250 and continue: 2507 / 834

Let's proceed to step 8:
The number 834 fits into 2507 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 92853.0
Subtract 2502 from 2507 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 834 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 92853.0
Subtract 0 from 50 to 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.

Let's proceed to step 10:
500 divided by 834 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 92853.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 92853.0 with a remainder of 0.5.
