We're dividing 71802159 by 581 
Let's see how many times 581 fits into 71802159.

On to step 1:
581 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 581

Moving on to step 2:
The number 581 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 581

Going ahead to step 3:
If we divide 718 by 581, we get 1 and a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 581 from 718, we get 137.
Append the next digit (0) from the dividend to 137 and continue with: 1370 / 581

Advancing to step 4:
When dividing 1370 by 581, we get 2 with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1162 from 1370, we get 208.
Append the next digit (2) from the dividend to 208 and continue with: 2082 / 581

Moving on to step 5:
If we divide 2082 by 581, we get 3 and a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
The remainder is 339 after subtracting 1743 from 2082.
Fetch the next digit (1) from the dividend, attach it to 339 and continue: 3391 / 581

Going ahead to step 6:
3391 divided by 581 is 5 with a remainder of 486.
Use 5 as the next digit of our solution. 
Result so far: 1235.0
Subtracting 2905 from 3391 leaves us with 486.
Bring next digit (5) of the dividend behind the 486 and repeat the process: 4865 / 581

Moving on to step 7:
When dividing 4865 by 581, we get 8 with a remainder of 217.
Write down 8 as next digit of the result. 
Result so far: 12358.0
Subtract 4648 from 4865 to get 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 581

Let's proceed to step 8:
581 can be fit into 2179 3 times, resulting in a remainder of 436.
Record the quotient 3 as the next digit in the result. 
Result so far: 123583.0
The remainder is 436 after subtracting 1743 from 2179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 9:
4360 divided by 581 is 7 with a remainder of 293.
The next digit of our result is 7. 
Result so far: 123583.7
The remainder is 293 after subtracting 4067 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 10:
2930 divided by 581 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 123583.75
Subtract 2905 from 2930 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
581 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 123583.75
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
If we divide 2500 by 581, we get 4 and a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 123583.7504
The remainder is 176 after subtracting 2324 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
581 goes into 1760 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 123583.75043
If we take 1743 away from 1760, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
581 goes into 170 0 times with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 123583.75043
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 15:
If we divide 1700 by 581, we get 2 and a remainder of 538.
Write down 2 as next digit of the result. 
Result so far: 123583.7504302
If we take 1162 away from 1700, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 16:
581 goes into 5380 9 times with a remainder of 151.
Record the quotient 9 as the next digit in the result. 
Result so far: 123583.75043029
If we subtract 5229 from 5380, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The quotient of the division is 123583.75043029, and the remainder is 1.51e-07.
