Let's divide 639251 by 19
We want to figure out the number of times 639251 can be divided by 19.

Let's proceed to step 1:
19 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 19

Advancing to step 2:
If we divide 63 by 19, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 57 from 63 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 19

Let's proceed to step 3:
When dividing 69 by 19, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 57 from 69 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 19

Going ahead to step 4:
When dividing 122 by 19, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 336.0
Subtracting 114 from 122 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 19

Advancing to step 5:
19 goes into 85 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 3364.0
If we take 76 away from 85, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 19

Moving on to step 6:
19 can be fit into 91 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 33644.0
If we take 76 away from 91, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 33644.7
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 33644.78
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 33644.789
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 33644.7894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
140 divided by 19 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 33644.78947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 33644.789473
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 19 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 33644.7894736
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
If we divide 160 by 19, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 33644.78947368
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 33644.78947368, with a leftover of 8e-09.
