We look at the division of 87437789 by 797 
Let's see how many times 797 fits into 87437789.

Advancing to step 1:
When dividing 8 by 797, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 797

On to step 2:
The number 797 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 797

Let's proceed to step 3:
If we divide 874 by 797, we get 1 and a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 797 from 874, we get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 797

On to step 4:
The number 797 fits into 773 0 times, leaving a remainder of 773.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 773 leaves us with 773.
Append the next digit (7) from the dividend to 773 and continue with: 7737 / 797

Going ahead to step 5:
7737 divided by 797 is 9 with a remainder of 564.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 7173 from 7737, we get 564.
Grab the next digit (7) from the dividend, add it to 564, then carry on: 5647 / 797

Going ahead to step 6:
The number 797 fits into 5647 7 times, leaving a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 1097.0
If we subtract 5579 from 5647, we get 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 797

Going ahead to step 7:
If we divide 688 by 797, we get 0 and a remainder of 688.
Put 0 as the next digit of the answer. 
Result so far: 10970.0
Subtract 0 from 688 to get 688.
Grab the next digit (9) from the dividend, add it to 688, then carry on: 6889 / 797

Moving on to step 8:
When dividing 6889 by 797, we get 8 with a remainder of 513.
Put 8 as the next digit of the answer. 
Result so far: 109708.0
If we subtract 6376 from 6889, we get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 9:
797 can be fit into 5130 6 times, resulting in a remainder of 348.
Put 6 as the next digit of the answer. 
Result so far: 109708.6
The remainder is 348 after subtracting 4782 from 5130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
797 goes into 3480 4 times with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 109708.64
If we subtract 3188 from 3480, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 11:
797 can be fit into 2920 3 times, resulting in a remainder of 529.
The next digit of our result is 3. 
Result so far: 109708.643
The remainder is 529 after subtracting 2391 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 12:
If we divide 5290 by 797, we get 6 and a remainder of 508.
The number 6 becomes the next digit in our result. 
Result so far: 109708.6436
Subtract 4782 from 5290 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 13:
When dividing 5080 by 797, we get 6 with a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 109708.64366
Subtract 4782 from 5080 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

The quotient of the division is 109708.64366, and the remainder is 0.000298.
