We look at the division of 81934622 by 431 
We want to divide 81934622 by 431.

Step 1:
The number 431 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 431

Going ahead to step 2:
If we divide 81 by 431, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 431

Advancing to step 3:
The number 431 fits into 819 1 times, leaving a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 431 from 819 to get 388.
Grab the next digit (3) from the dividend, add it to 388, then carry on: 3883 / 431

Let's proceed to step 4:
The number 431 fits into 3883 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 3879 from 3883 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 431

Moving on to step 5:
When dividing 44 by 431, we get 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 431

On to step 6:
446 divided by 431 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1901.0
Subtract 431 from 446 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 431

Let's proceed to step 7:
If we divide 152 by 431, we get 0 and a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 19010.0
If we take 0 away from 152, we end up with 152.
Fetch the next digit (2) from the dividend, attach it to 152 and continue: 1522 / 431

Going ahead to step 8:
The number 431 fits into 1522 3 times, leaving a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 190103.0
If we subtract 1293 from 1522, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 9:
431 can be fit into 2290 5 times, resulting in a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 190103.5
The remainder is 135 after subtracting 2155 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
When dividing 1350 by 431, we get 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 190103.53
Subtracting 1293 from 1350 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
When dividing 570 by 431, we get 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 190103.531
If we subtract 431 from 570, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 12:
431 goes into 1390 3 times with a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 190103.5313
Deduct 1293 from 1390 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 13:
The number 431 fits into 970 2 times, leaving a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 190103.53132
If we take 862 away from 970, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 14:
If we divide 1080 by 431, we get 2 and a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 190103.531322
If we subtract 862 from 1080, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

After the division, we end up with 190103.531322 and a remainder of 2.18e-05.
