99343788 ÷ 19 
We want to divide 99343788 by 19.

On to step 1:
When dividing 9 by 19, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 19

Going ahead to step 2:
19 can be fit into 99 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 95 away from 99, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 19

Let's proceed to step 3:
When dividing 43 by 19, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 38 from 43, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 19

Moving on to step 4:
When dividing 54 by 19, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 522.0
Subtracting 38 from 54 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 19

Step 5:
19 goes into 163 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 5228.0
Subtracting 152 from 163 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 19

Moving on to step 6:
If we divide 117 by 19, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 52286.0
Subtracting 114 from 117 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 19

Let's proceed to step 7:
The number 19 fits into 38 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 522862.0
If we take 38 away from 38, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 19

Step 8:
19 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 5228620.0
Deduct 0 from 8 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.

Step 9:
19 can be fit into 80 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 5228620.4
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.

Going ahead to step 10:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 5228620.42
Subtracting 38 from 40 leaves us 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 11:
20 divided by 19 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 5228620.421
If we take 19 away from 20, we end up with 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 12:
19 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5228620.421
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 13:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5228620.42105
If we subtract 95 from 100, we 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 14:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 5228620.421052
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.

Step 15:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 5228620.4210526
Deduct 114 from 120 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.

On to step 16:
When dividing 60 by 19, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 5228620.42105263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 5228620.42105263 with a balance of 3e-09.
