We divide 686138 by 87
We want to divide 686138 by 87.

Going ahead to step 1:
87 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 87

Advancing to step 2:
87 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 87

Advancing to step 3:
The number 87 fits into 686 7 times, leaving a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 77 after subtracting 609 from 686.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 87

Moving on to step 4:
87 can be fit into 771 8 times, resulting in a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtract 696 from 771 to get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 87

Moving on to step 5:
753 divided by 87 is 8 with a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 788.0
Subtract 696 from 753 to get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 87

Let's proceed to step 6:
87 goes into 578 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 7886.0
Subtract 522 from 578 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
560 divided by 87 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 7886.6
Subtract 522 from 560 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
When dividing 380 by 87, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 7886.64
Deduct 348 from 380 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
87 can be fit into 320 3 times, resulting in a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 7886.643
Subtracting 261 from 320 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
The number 87 fits into 590 6 times, leaving a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 7886.6436
Subtracting 522 from 590 leaves us 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.

Moving on to step 11:
680 divided by 87 is 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 7886.64367
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 12:
87 can be fit into 710 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 7886.643678
The remainder is 14 after subtracting 696 from 710.
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 13:
The number 87 fits into 140 1 times, leaving a remainder of 53.
The next digit of our result is 1. 
Result so far: 7886.6436781
Subtract 87 from 140 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
When dividing 530 by 87, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7886.64367816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 7886.64367816 with a remainder of 8e-09.
