We look at the division of 73365897 by 431 
We want to divide 73365897 by 431.

Going ahead to step 1:
431 goes into 7 0 times 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.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 431

Going ahead to step 2:
When dividing 73 by 431, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 431

Moving on to step 3:
733 divided by 431 is 1 with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 431 away from 733, we end up with 302.
Fetch the next digit (6) from the dividend, attach it to 302 and continue: 3026 / 431

On to step 4:
When dividing 3026 by 431, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 3017 from 3026 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 431

Let's proceed to step 5:
431 goes into 95 0 times with a remainder of 95.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we take 0 away from 95, we end up with 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 431

Advancing to step 6:
958 divided by 431 is 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 1702.0
The remainder is 96 after subtracting 862 from 958.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 431

On to step 7:
If we divide 969 by 431, we get 2 and a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 17022.0
If we subtract 862 from 969, we get 107.
Fetch the next digit (7) from the dividend, attach it to 107 and continue: 1077 / 431

On to step 8:
431 goes into 1077 2 times with a remainder of 215.
The number 2 becomes the next digit in our result. 
Result so far: 170222.0
The remainder is 215 after subtracting 862 from 1077.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
431 goes into 2150 4 times with a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 170222.4
Subtract 1724 from 2150 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 10:
If we divide 4260 by 431, we get 9 and a remainder of 381.
Put 9 as the next digit of the answer. 
Result so far: 170222.49
Subtract 3879 from 4260 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 11:
431 can be fit into 3810 8 times, resulting in a remainder of 362.
Put 8 as the next digit of the answer. 
Result so far: 170222.498
If we take 3448 away from 3810, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 12:
431 goes into 3620 8 times with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 170222.4988
Subtract 3448 from 3620 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 170222.4988, and the remainder is 0.00172.
