19339378 ÷ 124 
We want to figure out the number of times 19339378 can be divided by 124.

Advancing to step 1:
The number 124 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 124

Advancing to step 2:
If we divide 19 by 124, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 124

Step 3:
124 goes into 193 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 124 from 193 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 124

Step 4:
The number 124 fits into 693 5 times, leaving a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 73 after subtracting 620 from 693.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 124

Step 5:
The number 124 fits into 739 5 times, leaving a remainder of 119.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 620 from 739 to get 119.
Append the next digit (3) from the dividend to 119 and continue with: 1193 / 124

Moving on to step 6:
124 goes into 1193 9 times with a remainder of 77.
The next digit of our result is 9. 
Result so far: 1559.0
If we subtract 1116 from 1193, we get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 124

Advancing to step 7:
When dividing 777 by 124, we get 6 with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 15596.0
If we subtract 744 from 777, we get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 124

Step 8:
124 can be fit into 338 2 times, resulting in a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 155962.0
If we subtract 248 from 338, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
124 goes into 900 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 155962.7
If we subtract 868 from 900, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 124, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 155962.72
If we subtract 248 from 320, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
The number 124 fits into 720 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 155962.725
If we subtract 620 from 720, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
124 can be fit into 1000 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 155962.7258
If we subtract 992 from 1000, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 124 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 155962.7258
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
124 goes into 800 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 155962.725806
The remainder is 56 after subtracting 744 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 15:
560 divided by 124 is 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 155962.7258064
If we subtract 496 from 560, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
124 can be fit into 640 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 155962.72580645
The remainder is 20 after subtracting 620 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 155962.72580645 and a remainder of 2e-08.
