We look at the division of 860621 by 48 
We want to divide 860621 by 48.

Advancing to step 1:
8 divided by 48 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 48

Step 2:
The number 48 fits into 86 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 48 away from 86, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 48

Advancing to step 3:
The number 48 fits into 380 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 336 from 380 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 48

Step 4:
48 can be fit into 446 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 179.0
If we subtract 432 from 446, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 48

Advancing to step 5:
If we divide 142 by 48, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 1792.0
Subtracting 96 from 142 leaves us with 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 48

Going ahead to step 6:
When dividing 461 by 48, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 17929.0
The remainder is 29 after subtracting 432 from 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
When dividing 290 by 48, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 17929.6
The remainder is 2 after subtracting 288 from 290.
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 8:
If we divide 20 by 48, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17929.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
When dividing 200 by 48, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17929.604
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
If we divide 80 by 48, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 17929.6041
Subtract 48 from 80 to 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.

Going ahead to step 11:
48 goes into 320 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 17929.60416
Deduct 288 from 320 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 12:
48 goes into 320 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 17929.604166
Deduct 288 from 320 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.

Our division results in 17929.604166 with a remaining 3.2e-06.
