Let's divide 16390819 by 431
We want to divide 16390819 by 431.

Moving on to step 1:
431 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 431

Moving on to step 2:
431 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 431

Moving on to step 3:
163 divided by 431 is 0 with a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 163 to get 163.
Bring next digit (9) of the dividend behind the 163 and repeat the process: 1639 / 431

Let's proceed to step 4:
When dividing 1639 by 431, we get 3 with a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1293 away from 1639, we end up with 346.
Fetch the next digit (0) from the dividend, attach it to 346 and continue: 3460 / 431

Let's proceed to step 5:
431 can be fit into 3460 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 3448 from 3460 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 431

Going ahead to step 6:
431 can be fit into 128 0 times, resulting in a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 380.0
Subtract 0 from 128 to get 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 431

Moving on to step 7:
When dividing 1281 by 431, we get 2 with a remainder of 419.
The number 2 becomes the next digit in our result. 
Result so far: 3802.0
Subtracting 862 from 1281 leaves us with 419.
Bring next digit (9) of the dividend behind the 419 and repeat the process: 4199 / 431

Let's proceed to step 8:
431 goes into 4199 9 times with a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 38029.0
Deduct 3879 from 4199 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
431 goes into 3200 7 times with a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 38029.7
The remainder is 183 after subtracting 3017 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 10:
The number 431 fits into 1830 4 times, leaving a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 38029.74
Subtracting 1724 from 1830 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
431 can be fit into 1060 2 times, resulting in a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 38029.742
The remainder is 198 after subtracting 862 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 12:
If we divide 1980 by 431, we get 4 and a remainder of 256.
The next digit of our result is 4. 
Result so far: 38029.7424
Subtracting 1724 from 1980 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
When dividing 2560 by 431, we get 5 with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 38029.74245
If we subtract 2155 from 2560, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 14:
4050 divided by 431 is 9 with a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 38029.742459
If we take 3879 away from 4050, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 15:
1710 divided by 431 is 3 with a remainder of 417.
Put 3 as the next digit of the answer. 
Result so far: 38029.7424593
Subtracting 1293 from 1710 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 16:
If we divide 4170 by 431, we get 9 and a remainder of 291.
Use 9 as the next digit of our solution. 
Result so far: 38029.74245939
Subtract 3879 from 4170 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

In conclusion, the division gives 38029.74245939 with a balance of 2.91e-07.
