We look at the division of 86071087 by 558 
We want to divide 86071087 by 558.

Step 1:
When dividing 8 by 558, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 558

Step 2:
558 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 558

Advancing to step 3:
860 divided by 558 is 1 with a remainder of 302.
The next digit of our result is 1. 
Result so far: 1.0
If we take 558 away from 860, we end up with 302.
Fetch the next digit (7) from the dividend, attach it to 302 and continue: 3027 / 558

Let's proceed to step 4:
When dividing 3027 by 558, we get 5 with a remainder of 237.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 237 after subtracting 2790 from 3027.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 558

Going ahead to step 5:
558 goes into 2371 4 times with a remainder of 139.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 2232 from 2371, we get 139.
Append the next digit (0) from the dividend to 139 and continue with: 1390 / 558

Let's proceed to step 6:
The number 558 fits into 1390 2 times, leaving a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 1542.0
If we take 1116 away from 1390, we end up with 274.
Grab the next digit (8) from the dividend, add it to 274, then carry on: 2748 / 558

On to step 7:
2748 divided by 558 is 4 with a remainder of 516.
Write down 4 as next digit of the result. 
Result so far: 15424.0
If we take 2232 away from 2748, we end up with 516.
Fetch the next digit (7) from the dividend, attach it to 516 and continue: 5167 / 558

Let's proceed to step 8:
If we divide 5167 by 558, we get 9 and a remainder of 145.
The next digit of our result is 9. 
Result so far: 154249.0
Subtract 5022 from 5167 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
558 can be fit into 1450 2 times, resulting in a remainder of 334.
The next digit of our result is 2. 
Result so far: 154249.2
If we subtract 1116 from 1450, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
3340 divided by 558 is 5 with a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 154249.25
Subtracting 2790 from 3340 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
5500 divided by 558 is 9 with a remainder of 478.
The next digit of our result is 9. 
Result so far: 154249.259
Subtract 5022 from 5500 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 12:
4780 divided by 558 is 8 with a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 154249.2598
If we take 4464 away from 4780, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
When dividing 3160 by 558, we get 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 154249.25985
Subtract 2790 from 3160 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 14:
The number 558 fits into 3700 6 times, leaving a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 154249.259856
If we take 3348 away from 3700, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
When dividing 3520 by 558, we get 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 154249.2598566
If we subtract 3348 from 3520, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 154249.2598566 and a remainder of 1.72e-06.
