We're dividing 1623955 by 321 
We want to figure out the number of times 1623955 can be divided by 321.

Going ahead to step 1:
321 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 321

Going ahead to step 2:
321 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 321

Going ahead to step 3:
The number 321 fits into 162 0 times, leaving a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 162, we get 162.
Grab the next digit (3) from the dividend, add it to 162, then carry on: 1623 / 321

Let's proceed to step 4:
When dividing 1623 by 321, we get 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1605 from 1623 to get 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 321

Let's proceed to step 5:
The number 321 fits into 189 0 times, leaving a remainder of 189.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 189 and we're left with 189.
Fetch the next digit (5) from the dividend, attach it to 189 and continue: 1895 / 321

Going ahead to step 6:
1895 divided by 321 is 5 with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 505.0
The remainder is 290 after subtracting 1605 from 1895.
Fetch the next digit (5) from the dividend, attach it to 290 and continue: 2905 / 321

Let's proceed to step 7:
When dividing 2905 by 321, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 5059.0
If we take 2889 away from 2905, we end up with 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 8:
321 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 5059.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 9:
If we divide 1600 by 321, we get 4 and a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 5059.04
Subtract 1284 from 1600 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
321 can be fit into 3160 9 times, resulting in a remainder of 271.
The number 9 becomes the next digit in our result. 
Result so far: 5059.049
Deduct 2889 from 3160 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 11:
When dividing 2710 by 321, we get 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 5059.0498
If we take 2568 away from 2710, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
321 can be fit into 1420 4 times, resulting in a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 5059.04984
If we take 1284 away from 1420, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
321 goes into 1360 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 5059.049844
If we take 1284 away from 1360, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 5059.049844 with a remaining 7.6e-06.
