73163875 ÷ 635 
We want to figure out the number of times 73163875 can be divided by 635.

Step 1:
When dividing 7 by 635, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 635

Advancing to step 2:
73 divided by 635 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 635

Advancing to step 3:
If we divide 731 by 635, we get 1 and a remainder of 96.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 635 from 731 leaves us with 96.
Grab the next digit (6) from the dividend, add it to 96, then carry on: 966 / 635

Let's proceed to step 4:
635 can be fit into 966 1 times, resulting in a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 635 away from 966, we end up with 331.
Take the next digit (3) from the dividend and append it to 331, then repeat: 3313 / 635

Moving on to step 5:
635 goes into 3313 5 times with a remainder of 138.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we take 3175 away from 3313, we end up with 138.
Grab the next digit (8) from the dividend, add it to 138, then carry on: 1388 / 635

Going ahead to step 6:
1388 divided by 635 is 2 with a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 1152.0
Subtracting 1270 from 1388 leaves us with 118.
Grab the next digit (7) from the dividend, add it to 118, then carry on: 1187 / 635

Moving on to step 7:
The number 635 fits into 1187 1 times, leaving a remainder of 552.
The next digit of our result is 1. 
Result so far: 11521.0
Subtract 635 from 1187 to get 552.
Grab the next digit (5) from the dividend, add it to 552, then carry on: 5525 / 635

Moving on to step 8:
The number 635 fits into 5525 8 times, leaving a remainder of 445.
Write down 8 as next digit of the result. 
Result so far: 115218.0
Subtracting 5080 from 5525 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 9:
If we divide 4450 by 635, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 115218.7
If we take 4445 away from 4450, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 635 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 115218.7
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
635 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 115218.7
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 115218.7 and a remainder of 0.05.
