641099 ÷ 19 
We're looking to find how many times 19 goes into 641099.

Going ahead to step 1:
19 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 19

Let's proceed to step 2:
19 goes into 64 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 57 from 64, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 19

Advancing to step 3:
19 can be fit into 71 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 57 from 71 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 19

On to step 4:
When dividing 140 by 19, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 337.0
Deduct 133 from 140 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 19

On to step 5:
The number 19 fits into 79 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 3374.0
Deduct 76 from 79 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 19

Moving on to step 6:
19 can be fit into 39 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 33742.0
Subtract 38 from 39 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.

Moving on to step 7:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 33742.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
If we divide 100 by 19, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 33742.05
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 33742.052
Subtracting 38 from 50 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
19 goes into 120 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 33742.0526
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.

On to step 11:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 33742.05263
Deduct 57 from 60 and we're left 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.

Advancing to step 12:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 33742.052631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
If we divide 110 by 19, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 33742.0526315
Subtracting 95 from 110 leaves us 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 14:
150 divided by 19 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 33742.05263157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 33742.05263157, with a leftover of 1.7e-08.
