We look at the division of 643110 by 19 
We want to divide 643110 by 19.

Moving on to step 1:
When dividing 6 by 19, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 19

On to step 2:
19 can be fit into 64 3 times, resulting in 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.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 19

Step 3:
19 goes into 73 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 57 from 73 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 19

Moving on to step 4:
The number 19 fits into 161 8 times, leaving a remainder of 9.
The next digit of our result is 8. 
Result so far: 338.0
If we subtract 152 from 161, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

On to step 5:
When dividing 91 by 19, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 3384.0
Deduct 76 from 91 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 19

Moving on to step 6:
150 divided by 19 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 33847.0
If we take 133 away from 150, we end up 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.

Step 7:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 33847.8
Deduct 152 from 170 and we're left with 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 8:
180 divided by 19 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 33847.89
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
19 can be fit into 90 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 33847.894
If we take 76 away from 90, we end up with 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 10:
140 divided by 19 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 33847.8947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
When dividing 70 by 19, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 33847.89473
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
When dividing 130 by 19, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 33847.894736
The remainder is 16 after subtracting 114 from 130.
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 13:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 33847.8947368
If we take 152 away from 160, we end up 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.

Step 14:
When dividing 80 by 19, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 33847.89473684
Subtracting 76 from 80 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 33847.89473684 with a remainder of 4e-09.
