53913009 ÷ 473 
Let's see how many times 473 fits into 53913009.

Step 1:
473 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 473

Going ahead to step 2:
If we divide 53 by 473, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 473

Moving on to step 3:
The number 473 fits into 539 1 times, leaving a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 473 from 539 leaves us with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 473

Let's proceed to step 4:
473 can be fit into 661 1 times, resulting in a remainder of 188.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 473 from 661 leaves us with 188.
Take the next digit (3) from the dividend and append it to 188, then repeat: 1883 / 473

Moving on to step 5:
473 can be fit into 1883 3 times, resulting in a remainder of 464.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Deduct 1419 from 1883 and we're left with 464.
Append the next digit (0) from the dividend to 464 and continue with: 4640 / 473

Going ahead to step 6:
If we divide 4640 by 473, we get 9 and a remainder of 383.
Put 9 as the next digit of the answer. 
Result so far: 1139.0
If we take 4257 away from 4640, we end up with 383.
Grab the next digit (0) from the dividend, add it to 383, then carry on: 3830 / 473

Advancing to step 7:
The number 473 fits into 3830 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 11398.0
If we subtract 3784 from 3830, we get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 473

Advancing to step 8:
473 goes into 469 0 times with a remainder of 469.
Use 0 as the next digit of our solution. 
Result so far: 113980.0
Subtracting 0 from 469 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Let's proceed to step 9:
When dividing 4690 by 473, we get 9 with a remainder of 433.
The next digit of our result is 9. 
Result so far: 113980.9
The remainder is 433 after subtracting 4257 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 10:
If we divide 4330 by 473, we get 9 and a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 113980.99
If we take 4257 away from 4330, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 113980.99 with a remainder of 0.073.
