19999183 ÷ 280 
We want to figure out the number of times 19999183 can be divided by 280.

Advancing to step 1:
280 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 280

Going ahead to step 2:
When dividing 19 by 280, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 280

Let's proceed to step 3:
280 can be fit into 199 0 times, resulting in a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 280

Going ahead to step 4:
If we divide 1999 by 280, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 1960 from 1999, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 280

Step 5:
When dividing 399 by 280, we get 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 280 from 399 leaves us with 119.
Bring next digit (1) of the dividend behind the 119 and repeat the process: 1191 / 280

Going ahead to step 6:
If we divide 1191 by 280, we get 4 and a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 714.0
If we take 1120 away from 1191, we end up with 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 280

Advancing to step 7:
The number 280 fits into 718 2 times, leaving a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 7142.0
If we subtract 560 from 718, we get 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 280

Let's proceed to step 8:
If we divide 1583 by 280, we get 5 and a remainder of 183.
Put 5 as the next digit of the answer. 
Result so far: 71425.0
If we subtract 1400 from 1583, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
If we divide 1830 by 280, we get 6 and a remainder of 150.
Put 6 as the next digit of the answer. 
Result so far: 71425.6
Subtract 1680 from 1830 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
280 goes into 1500 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 71425.65
The remainder is 100 after subtracting 1400 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
280 goes into 1000 3 times with a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 71425.653
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 71425.6535
Subtracting 1400 from 1600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
280 goes into 2000 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 71425.65357
If we subtract 1960 from 2000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
If we divide 400 by 280, we get 1 and a remainder of 120.
The next digit of our result is 1. 
Result so far: 71425.653571
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
1200 divided by 280 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 71425.6535714
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
280 goes into 800 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 71425.65357142
Deduct 560 from 800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 71425.65357142 with a remainder of 2.4e-07.
