We look at the division of 16434546 by 838 
We want to figure out the number of times 16434546 can be divided by 838.

Step 1:
The number 838 fits into 1 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 838

Going ahead to step 2:
If we divide 16 by 838, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 838

Advancing to step 3:
164 divided by 838 is 0 with a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 164 to get 164.
Bring next digit (3) of the dividend behind the 164 and repeat the process: 1643 / 838

Step 4:
838 goes into 1643 1 times with a remainder of 805.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 838 from 1643, we get 805.
Bring next digit (4) of the dividend behind the 805 and repeat the process: 8054 / 838

On to step 5:
838 can be fit into 8054 9 times, resulting in a remainder of 512.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 512 after subtracting 7542 from 8054.
Append the next digit (5) from the dividend to 512 and continue with: 5125 / 838

Going ahead to step 6:
If we divide 5125 by 838, we get 6 and a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 196.0
If we take 5028 away from 5125, we end up with 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 838

Going ahead to step 7:
974 divided by 838 is 1 with a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 1961.0
Deduct 838 from 974 and we're left with 136.
Bring next digit (6) of the dividend behind the 136 and repeat the process: 1366 / 838

Moving on to step 8:
When dividing 1366 by 838, we get 1 with a remainder of 528.
Record the quotient 1 as the next digit in the result. 
Result so far: 19611.0
Subtracting 838 from 1366 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 9:
If we divide 5280 by 838, we get 6 and a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 19611.6
Subtracting 5028 from 5280 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 10:
838 goes into 2520 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 19611.63
If we take 2514 away from 2520, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
60 divided by 838 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 19611.63
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 838 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 19611.63
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 19611.63, with a leftover of 0.006.
