We're dividing 86638 by 46 
We want to divide 86638 by 46.

Going ahead to step 1:
The number 46 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 46

Going ahead to step 2:
46 can be fit into 86 1 times, resulting in a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 46 from 86 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 46

Step 3:
406 divided by 46 is 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 368 away from 406, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 46

Step 4:
If we divide 383 by 46, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtracting 368 from 383 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 46

Going ahead to step 5:
If we divide 158 by 46, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 1883.0
Subtracting 138 from 158 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 6:
46 can be fit into 200 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1883.4
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 46, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 1883.43
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
If we divide 220 by 46, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1883.434
Deduct 184 from 220 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 46, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 1883.4347
The remainder is 38 after subtracting 322 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 46 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1883.43478
If we subtract 368 from 380, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
120 divided by 46 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1883.434782
If we take 92 away from 120, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 46, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1883.4347826
Subtract 276 from 280 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 46 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1883.4347826
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 1883.4347826 and a remainder of 4e-08.
