We're dividing 71451251 by 587 
We want to divide 71451251 by 587.

Let's proceed to step 1:
When dividing 7 by 587, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 587

Going ahead to step 2:
The number 587 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 587

Moving on to step 3:
587 can be fit into 714 1 times, resulting in a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 587 from 714 to get 127.
Take the next digit (5) from the dividend and append it to 127, then repeat: 1275 / 587

Advancing to step 4:
If we divide 1275 by 587, we get 2 and a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1174 from 1275 to get 101.
Include the next digit (1) from the dividend after 101, then repeat: 1011 / 587

Step 5:
When dividing 1011 by 587, we get 1 with a remainder of 424.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 587 from 1011 to get 424.
Bring next digit (2) of the dividend behind the 424 and repeat the process: 4242 / 587

Let's proceed to step 6:
4242 divided by 587 is 7 with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 1217.0
Deduct 4109 from 4242 and we're left with 133.
Append the next digit (5) from the dividend to 133 and continue with: 1335 / 587

Going ahead to step 7:
1335 divided by 587 is 2 with a remainder of 161.
Record the quotient 2 as the next digit in the result. 
Result so far: 12172.0
The remainder is 161 after subtracting 1174 from 1335.
Fetch the next digit (1) from the dividend, attach it to 161 and continue: 1611 / 587

Step 8:
587 goes into 1611 2 times with a remainder of 437.
Write down 2 as next digit of the result. 
Result so far: 121722.0
If we take 1174 away from 1611, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 9:
If we divide 4370 by 587, we get 7 and a remainder of 261.
Record the quotient 7 as the next digit in the result. 
Result so far: 121722.7
Deduct 4109 from 4370 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 10:
When dividing 2610 by 587, we get 4 with a remainder of 262.
The next digit of our result is 4. 
Result so far: 121722.74
Deduct 2348 from 2610 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 11:
2620 divided by 587 is 4 with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 121722.744
Subtracting 2348 from 2620 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 121722.744, with a leftover of 0.0272.
