42160966 divided by 809 
Our goal is to divide 42160966 by 809.

Let's proceed to step 1:
809 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 809

Moving on to step 2:
42 divided by 809 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 809

Let's proceed to step 3:
The number 809 fits into 421 0 times, leaving a remainder of 421.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 421 to get 421.
Include the next digit (6) from the dividend after 421, then repeat: 4216 / 809

Going ahead to step 4:
The number 809 fits into 4216 5 times, leaving a remainder of 171.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4045 from 4216 to get 171.
Take the next digit (0) from the dividend and append it to 171, then repeat: 1710 / 809

Step 5:
809 goes into 1710 2 times with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 1618 from 1710, we get 92.
Append the next digit (9) from the dividend to 92 and continue with: 929 / 809

On to step 6:
When dividing 929 by 809, we get 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtract 809 from 929 to get 120.
Take the next digit (6) from the dividend and append it to 120, then repeat: 1206 / 809

Going ahead to step 7:
The number 809 fits into 1206 1 times, leaving a remainder of 397.
The next digit of our result is 1. 
Result so far: 5211.0
Subtracting 809 from 1206 leaves us with 397.
Bring next digit (6) of the dividend behind the 397 and repeat the process: 3976 / 809

Step 8:
When dividing 3976 by 809, we get 4 with a remainder of 740.
Use 4 as the next digit of our solution. 
Result so far: 52114.0
Subtract 3236 from 3976 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 9:
If we divide 7400 by 809, we get 9 and a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 52114.9
Subtract 7281 from 7400 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 10:
The number 809 fits into 1190 1 times, leaving a remainder of 381.
Record the quotient 1 as the next digit in the result. 
Result so far: 52114.91
Deduct 809 from 1190 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 11:
809 goes into 3810 4 times with a remainder of 574.
Record the quotient 4 as the next digit in the result. 
Result so far: 52114.914
If we subtract 3236 from 3810, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 12:
5740 divided by 809 is 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 52114.9147
If we take 5663 away from 5740, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 13:
809 can be fit into 770 0 times, resulting in a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 52114.9147
The remainder is 770 after subtracting 0 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 14:
7700 divided by 809 is 9 with a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 52114.914709
Subtract 7281 from 7700 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 15:
809 can be fit into 4190 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 52114.9147095
Deduct 4045 from 4190 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 16:
When dividing 1450 by 809, we get 1 with a remainder of 641.
Write down 1 as next digit of the result. 
Result so far: 52114.91470951
If we take 809 away from 1450, we end up with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

The final result is 52114.91470951 with a remainder of 6.41e-07.
