Advancing to step 4:
4512 divided by 834 is 5 with a remainder of 342.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4170 from 4512 to get 342.
Take the next digit (3) from the dividend and append it to 342, then repeat: 3423 / 834

On to step 5:
The number 834 fits into 3423 4 times, leaving a remainder of 87.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 3336 away from 3423, we end up with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 834

Going ahead to step 6:
When dividing 879 by 834, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 541.0
Subtract 834 from 879 to get 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 834

Advancing to step 7:
834 can be fit into 458 0 times, resulting in a remainder of 458.
Use 0 as the next digit of our solution. 
Result so far: 5410.0
If we subtract 0 from 458, we get 458.
Fetch the next digit (5) from the dividend, attach it to 458 and continue: 4585 / 834

Let's proceed to step 8:
The number 834 fits into 4585 5 times, leaving a remainder of 415.
The next digit of our result is 5. 
Result so far: 54105.0
If we subtract 4170 from 4585, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
834 can be fit into 4150 4 times, resulting in a remainder of 814.
Write down 4 as next digit of the result. 
Result so far: 54105.4
Subtracting 3336 from 4150 leaves us with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Let's proceed to step 10:
834 goes into 8140 9 times with a remainder of 634.
The number 9 becomes the next digit in our result. 
Result so far: 54105.49
The remainder is 634 after subtracting 7506 from 8140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

On to step 11:
834 can be fit into 6340 7 times, resulting in a remainder of 502.
The number 7 becomes the next digit in our result. 
Result so far: 54105.497
Deduct 5838 from 6340 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 12:
The number 834 fits into 5020 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 54105.4976
Deduct 5004 from 5020 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
If we divide 160 by 834, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 54105.4976
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
834 goes into 1600 1 times with a remainder of 766.
Use 1 as the next digit of our solution. 
Result so far: 54105.497601
If we subtract 834 from 1600, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 15:
7660 divided by 834 is 9 with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 54105.4976019
Subtracting 7506 from 7660 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 16:
834 can be fit into 1540 1 times, resulting in a remainder of 706.
Use 1 as the next digit of our solution. 
Result so far: 54105.49760191
The remainder is 706 after subtracting 834 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

The quotient of the division is 54105.49760191, and the remainder is 7.06e-07.
