Use 2 as the next digit of our solution. 
Result so far: 8912.0
Deduct 1832 from 2408 and we're left with 576.
Bring next digit (3) of the dividend behind the 576 and repeat the process: 5763 / 916

Let's proceed to step 8:
If we divide 5763 by 916, we get 6 and a remainder of 267.
Write down 6 as next digit of the result. 
Result so far: 89126.0
If we take 5496 away from 5763, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
2670 divided by 916 is 2 with a remainder of 838.
Use 2 as the next digit of our solution. 
Result so far: 89126.2
Deduct 1832 from 2670 and we're left with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Going ahead to step 10:
The number 916 fits into 8380 9 times, leaving a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 89126.29
Subtract 8244 from 8380 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
The number 916 fits into 1360 1 times, leaving a remainder of 444.
The next digit of our result is 1. 
Result so far: 89126.291
If we take 916 away from 1360, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 12:
The number 916 fits into 4440 4 times, leaving a remainder of 776.
The next digit of our result is 4. 
Result so far: 89126.2914
If we take 3664 away from 4440, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

On to step 13:
The number 916 fits into 7760 8 times, leaving a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 89126.29148
The remainder is 432 after subtracting 7328 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
4320 divided by 916 is 4 with a remainder of 656.
Record the quotient 4 as the next digit in the result. 
Result so far: 89126.291484
The remainder is 656 after subtracting 3664 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 15:
916 goes into 6560 7 times with a remainder of 148.
The next digit of our result is 7. 
Result so far: 89126.2914847
The remainder is 148 after subtracting 6412 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 16:
The number 916 fits into 1480 1 times, leaving a remainder of 564.
Put 1 as the next digit of the answer. 
Result so far: 89126.29148471
The remainder is 564 after subtracting 916 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The quotient of the division is 89126.29148471, and the remainder is 5.64e-07.
