71872598 ÷ 798 
Our goal is to divide 71872598 by 798.

On to step 1:
798 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 798

Going ahead to step 2:
798 goes into 71 0 times with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 798

Going ahead to step 3:
718 divided by 798 is 0 with a remainder of 718.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 718, we get 718.
Include the next digit (7) from the dividend after 718, then repeat: 7187 / 798

Advancing to step 4:
The number 798 fits into 7187 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 5 after subtracting 7182 from 7187.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 798

Let's proceed to step 5:
52 divided by 798 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 90.0
If we take 0 away from 52, we end up with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 798

Going ahead to step 6:
The number 798 fits into 525 0 times, leaving a remainder of 525.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
If we subtract 0 from 525, we get 525.
Grab the next digit (9) from the dividend, add it to 525, then carry on: 5259 / 798

Going ahead to step 7:
If we divide 5259 by 798, we get 6 and a remainder of 471.
Use 6 as the next digit of our solution. 
Result so far: 9006.0
Subtract 4788 from 5259 to get 471.
Grab the next digit (8) from the dividend, add it to 471, then carry on: 4718 / 798

Going ahead to step 8:
The number 798 fits into 4718 5 times, leaving a remainder of 728.
Use 5 as the next digit of our solution. 
Result so far: 90065.0
Subtract 3990 from 4718 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 9:
7280 divided by 798 is 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 90065.9
If we subtract 7182 from 7280, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
798 can be fit into 980 1 times, resulting in a remainder of 182.
The next digit of our result is 1. 
Result so far: 90065.91
If we take 798 away from 980, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 11:
The number 798 fits into 1820 2 times, leaving a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 90065.912
If we take 1596 away from 1820, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
If we divide 2240 by 798, we get 2 and a remainder of 644.
The number 2 becomes the next digit in our result. 
Result so far: 90065.9122
Subtract 1596 from 2240 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

After the division, we end up with 90065.9122 and a remainder of 0.00644.
