We're dividing 646160 by 19 
Let's see how many times 19 fits into 646160.

On to step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 19

Step 2:
19 goes into 64 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 57 from 64 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 19

On to step 3:
19 goes into 76 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 76 away from 76, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 19

Moving on to step 4:
1 divided by 19 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 340.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 19

Let's proceed to step 5:
If we divide 16 by 19, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 3400.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 19

Let's proceed to step 6:
The number 19 fits into 160 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 34008.0
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 34008.4
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 34008.42
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
19 goes into 20 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 34008.421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
When dividing 10 by 19, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 34008.421
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
19 goes into 100 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 34008.42105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 19 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 34008.421052
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 34008.4210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
When dividing 60 by 19, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 34008.42105263
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 34008.42105263 with a remaining 3e-09.
