Let's divide 686913 by 19
We want to figure out the number of times 686913 can be divided by 19.

On to step 1:
The number 19 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 19

Advancing to step 2:
19 can be fit into 68 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 57 from 68 leaves us with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 19

Advancing to step 3:
116 divided by 19 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 114 from 116 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 19

Step 4:
If we divide 29 by 19, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we subtract 19 from 29, we get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 19

Advancing to step 5:
19 goes into 101 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 3615.0
Deduct 95 from 101 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 19

Moving on to step 6:
When dividing 63 by 19, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 36153.0
Deduct 57 from 63 and we're left 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.

Let's proceed to step 7:
If we divide 60 by 19, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 36153.3
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 19 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 36153.31
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
When dividing 110 by 19, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 36153.315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 36153.3157
The remainder is 17 after subtracting 133 from 150.
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 11:
19 goes into 170 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 36153.31578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 36153.315789
Subtracting 171 from 180 leaves us 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 13:
90 divided by 19 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 36153.3157894
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.

Step 14:
The number 19 fits into 140 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 36153.31578947
Subtract 133 from 140 to 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.

In conclusion, the division gives 36153.31578947 with a balance of 7e-09.
