Let's divide 45490199 by 431
Our goal is to divide 45490199 by 431.

Let's proceed to step 1:
4 divided by 431 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 431

Advancing to step 2:
45 divided by 431 is 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 431

Moving on to step 3:
If we divide 454 by 431, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 431 from 454 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 431

Let's proceed to step 4:
431 goes into 239 0 times with a remainder of 239.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 239 leaves us with 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 431

Advancing to step 5:
When dividing 2390 by 431, we get 5 with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 2155 from 2390 to get 235.
Include the next digit (1) from the dividend after 235, then repeat: 2351 / 431

Step 6:
The number 431 fits into 2351 5 times, leaving a remainder of 196.
Put 5 as the next digit of the answer. 
Result so far: 1055.0
Subtract 2155 from 2351 to get 196.
Grab the next digit (9) from the dividend, add it to 196, then carry on: 1969 / 431

Advancing to step 7:
431 can be fit into 1969 4 times, resulting in a remainder of 245.
Record the quotient 4 as the next digit in the result. 
Result so far: 10554.0
Subtracting 1724 from 1969 leaves us with 245.
Append the next digit (9) from the dividend to 245 and continue with: 2459 / 431

Step 8:
If we divide 2459 by 431, we get 5 and a remainder of 304.
Put 5 as the next digit of the answer. 
Result so far: 105545.0
The remainder is 304 after subtracting 2155 from 2459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
When dividing 3040 by 431, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 105545.7
If we subtract 3017 from 3040, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
If we divide 230 by 431, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 105545.7
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
431 can be fit into 2300 5 times, resulting in a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 105545.705
The remainder is 145 after subtracting 2155 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
1450 divided by 431 is 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 105545.7053
Deduct 1293 from 1450 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
If we divide 1570 by 431, we get 3 and a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 105545.70533
If we subtract 1293 from 1570, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

After the division, we end up with 105545.70533 and a remainder of 0.000277.
