We're dividing 686165 by 42 
We want to divide 686165 by 42.

Let's proceed to step 1:
42 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 42

Step 2:
42 goes into 68 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 68, we get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 42

On to step 3:
42 can be fit into 266 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 14 after subtracting 252 from 266.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 42

Going ahead to step 4:
42 can be fit into 141 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Deduct 126 from 141 and we're left with 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 42

Going ahead to step 5:
If we divide 156 by 42, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 1633.0
Deduct 126 from 156 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 42

Let's proceed to step 6:
If we divide 305 by 42, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 16337.0
If we take 294 away from 305, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
The number 42 fits into 110 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 16337.2
If we subtract 84 from 110, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
42 goes into 260 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 16337.26
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 16337.261
If we subtract 42 from 80, we 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 10:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 16337.2619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16337.2619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 16337.261904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 16337.2619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 16337.26190476
The remainder is 8 after subtracting 252 from 260.
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 16337.26190476 with a remainder of 8e-09.
