Step 5:
763 goes into 7288 9 times with a remainder of 421.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 6867 away from 7288, we end up with 421.
Take the next digit (8) from the dividend and append it to 421, then repeat: 4218 / 763

Let's proceed to step 6:
763 can be fit into 4218 5 times, resulting in a remainder of 403.
The number 5 becomes the next digit in our result. 
Result so far: 595.0
If we subtract 3815 from 4218, we get 403.
Include the next digit (6) from the dividend after 403, then repeat: 4036 / 763

Moving on to step 7:
763 goes into 4036 5 times with a remainder of 221.
Write down 5 as next digit of the result. 
Result so far: 5955.0
If we take 3815 away from 4036, we end up with 221.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 763

Let's proceed to step 8:
2219 divided by 763 is 2 with a remainder of 693.
Use 2 as the next digit of our solution. 
Result so far: 59552.0
Deduct 1526 from 2219 and we're left with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Going ahead to step 9:
The number 763 fits into 6930 9 times, leaving a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 59552.9
If we take 6867 away from 6930, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
630 divided by 763 is 0 with a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 59552.9
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 11:
763 can be fit into 6300 8 times, resulting in a remainder of 196.
The next digit of our result is 8. 
Result so far: 59552.908
If we take 6104 away from 6300, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
When dividing 1960 by 763, we get 2 with a remainder of 434.
The number 2 becomes the next digit in our result. 
Result so far: 59552.9082
Deduct 1526 from 1960 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 13:
If we divide 4340 by 763, we get 5 and a remainder of 525.
Record the quotient 5 as the next digit in the result. 
Result so far: 59552.90825
Deduct 3815 from 4340 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 14:
When dividing 5250 by 763, we get 6 with a remainder of 672.
The number 6 becomes the next digit in our result. 
Result so far: 59552.908256
If we take 4578 away from 5250, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 15:
When dividing 6720 by 763, we get 8 with a remainder of 616.
Write down 8 as next digit of the result. 
Result so far: 59552.9082568
If we take 6104 away from 6720, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 16:
The number 763 fits into 6160 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 59552.90825688
Deduct 6104 from 6160 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 59552.90825688 with a balance of 5.6e-08.
