We look at the division of 151718 by 86 
We want to divide 151718 by 86.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 86

Moving on to step 2:
The number 86 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 86

Moving on to step 3:
86 goes into 151 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 151 to get 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 86

Advancing to step 4:
When dividing 657 by 86, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 602 away from 657, we end up with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 86

On to step 5:
If we divide 551 by 86, we get 6 and a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
Deduct 516 from 551 and we're left with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 86

On to step 6:
86 goes into 358 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1764.0
Subtracting 344 from 358 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1764.1
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
540 divided by 86 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1764.16
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 86 fits into 240 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 1764.162
If we subtract 172 from 240, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
680 divided by 86 is 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 1764.1627
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
The number 86 fits into 780 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1764.16279
Deduct 774 from 780 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
86 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 1764.16279
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
86 can be fit into 600 6 times, resulting in a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 1764.1627906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 1764.16279069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 1764.16279069 and a remainder of 6.6e-08.
