1587172 ÷ 798 
Let's see how many times 798 fits into 1587172.

Let's proceed to step 1:
798 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.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 798

Advancing to step 2:
If we divide 15 by 798, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 798

Let's proceed to step 3:
When dividing 158 by 798, we get 0 with a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Take the next digit (7) from the dividend and append it to 158, then repeat: 1587 / 798

Moving on to step 4:
If we divide 1587 by 798, we get 1 and a remainder of 789.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 798 from 1587 and we're left with 789.
Bring next digit (1) of the dividend behind the 789 and repeat the process: 7891 / 798

Step 5:
798 can be fit into 7891 9 times, resulting in a remainder of 709.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 7182 from 7891 to get 709.
Grab the next digit (7) from the dividend, add it to 709, then carry on: 7097 / 798

On to step 6:
If we divide 7097 by 798, we get 8 and a remainder of 713.
The next digit of our result is 8. 
Result so far: 198.0
If we subtract 6384 from 7097, we get 713.
Grab the next digit (2) from the dividend, add it to 713, then carry on: 7132 / 798

Advancing to step 7:
The number 798 fits into 7132 8 times, leaving a remainder of 748.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
Subtract 6384 from 7132 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Advancing to step 8:
The number 798 fits into 7480 9 times, leaving a remainder of 298.
Write down 9 as next digit of the result. 
Result so far: 1988.9
The remainder is 298 after subtracting 7182 from 7480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 9:
798 can be fit into 2980 3 times, resulting in a remainder of 586.
Write down 3 as next digit of the result. 
Result so far: 1988.93
Subtracting 2394 from 2980 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 10:
The number 798 fits into 5860 7 times, leaving a remainder of 274.
The number 7 becomes the next digit in our result. 
Result so far: 1988.937
If we subtract 5586 from 5860, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
2740 divided by 798 is 3 with a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 1988.9373
If we take 2394 away from 2740, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 12:
The number 798 fits into 3460 4 times, leaving a remainder of 268.
The next digit of our result is 4. 
Result so far: 1988.93734
If we take 3192 away from 3460, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 13:
When dividing 2680 by 798, we get 3 with a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 1988.937343
If we take 2394 away from 2680, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 14:
The number 798 fits into 2860 3 times, leaving a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 1988.9373433
Subtract 2394 from 2860 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

The final outcome is 1988.9373433, with a leftover of 4.66e-06.
