71007087 ÷ 486 
Our goal is to divide 71007087 by 486.

On to step 1:
The number 486 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 486

Moving on to step 2:
When dividing 71 by 486, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 486

Going ahead to step 3:
If we divide 710 by 486, we get 1 and a remainder of 224.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 486 away from 710, we end up with 224.
Grab the next digit (0) from the dividend, add it to 224, then carry on: 2240 / 486

Advancing to step 4:
2240 divided by 486 is 4 with a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 1944 away from 2240, we end up with 296.
Fetch the next digit (7) from the dividend, attach it to 296 and continue: 2967 / 486

Going ahead to step 5:
2967 divided by 486 is 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we take 2916 away from 2967, we end up with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 486

Going ahead to step 6:
If we divide 510 by 486, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
If we subtract 486 from 510, we get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 486

Advancing to step 7:
The number 486 fits into 248 0 times, leaving a remainder of 248.
Put 0 as the next digit of the answer. 
Result so far: 14610.0
The remainder is 248 after subtracting 0 from 248.
Take the next digit (7) from the dividend and append it to 248, then repeat: 2487 / 486

Moving on to step 8:
If we divide 2487 by 486, we get 5 and a remainder of 57.
The next digit of our result is 5. 
Result so far: 146105.0
Deduct 2430 from 2487 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 486, we get 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 146105.1
If we take 486 away from 570, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
486 goes into 840 1 times with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 146105.11
Subtracting 486 from 840 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 146105.11 with a balance of 0.354.
