We look at the division of 45455909 by 763 
We want to divide 45455909 by 763.

Going ahead to step 1:
4 divided by 763 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 763

Advancing to step 2:
If we divide 45 by 763, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 763

Going ahead to step 3:
If we divide 454 by 763, we get 0 and a remainder of 454.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 454 and we're left with 454.
Fetch the next digit (5) from the dividend, attach it to 454 and continue: 4545 / 763

Advancing to step 4:
4545 divided by 763 is 5 with a remainder of 730.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 3815 from 4545, we get 730.
Grab the next digit (5) from the dividend, add it to 730, then carry on: 7305 / 763

Let's proceed to step 5:
763 can be fit into 7305 9 times, resulting in a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtract 6867 from 7305 to get 438.
Include the next digit (9) from the dividend after 438, then repeat: 4389 / 763

Moving on to step 6:
If we divide 4389 by 763, we get 5 and a remainder of 574.
The next digit of our result is 5. 
Result so far: 595.0
If we take 3815 away from 4389, we end up with 574.
Bring next digit (0) of the dividend behind the 574 and repeat the process: 5740 / 763

Moving on to step 7:
763 can be fit into 5740 7 times, resulting in a remainder of 399.
The next digit of our result is 7. 
Result so far: 5957.0
Subtract 5341 from 5740 to get 399.
Bring next digit (9) of the dividend behind the 399 and repeat the process: 3999 / 763

Let's proceed to step 8:
The number 763 fits into 3999 5 times, leaving a remainder of 184.
The number 5 becomes the next digit in our result. 
Result so far: 59575.0
If we take 3815 away from 3999, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
The number 763 fits into 1840 2 times, leaving a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 59575.2
If we subtract 1526 from 1840, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 10:
3140 divided by 763 is 4 with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 59575.24
If we subtract 3052 from 3140, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
If we divide 880 by 763, we get 1 and a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 59575.241
The remainder is 117 after subtracting 763 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 12:
763 can be fit into 1170 1 times, resulting in a remainder of 407.
The next digit of our result is 1. 
Result so far: 59575.2411
If we subtract 763 from 1170, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Our division results in 59575.2411 with a remaining 0.00407.
