671158 divided by 86 
Let's see how many times 86 fits into 671158.

Moving on to step 1:
86 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 86

On to step 2:
The number 86 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 86

Let's proceed to step 3:
If we divide 671 by 86, we get 7 and a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 69 after subtracting 602 from 671.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 86

Let's proceed to step 4:
86 goes into 691 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 688 away from 691, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 86

On to step 5:
35 divided by 86 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 780.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 86

Let's proceed to step 6:
86 can be fit into 358 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 7804.0
If we subtract 344 from 358, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
86 goes into 140 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 7804.1
Deduct 86 from 140 and we're left 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.

On to step 8:
86 goes into 540 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7804.16
If we subtract 516 from 540, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
86 goes into 240 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 7804.162
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
86 goes into 680 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 7804.1627
Deduct 602 from 680 and we're left 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.

Moving on to step 11:
If we divide 780 by 86, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 7804.16279
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.

Let's proceed to step 12:
When dividing 60 by 86, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7804.16279
Deduct 0 from 60 and we're left 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.

Step 13:
When dividing 600 by 86, we get 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 7804.1627906
If we take 516 away from 600, 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.

Advancing to step 14:
When dividing 840 by 86, we get 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 7804.16279069
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.

The final outcome is 7804.16279069, with a leftover of 6.6e-08.
