51627859 ÷ 321 
We want to divide 51627859 by 321.

Step 1:
321 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 321

Moving on to step 2:
When dividing 51 by 321, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 321

Going ahead to step 3:
321 goes into 516 1 times with a remainder of 195.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 321 from 516 and we're left with 195.
Bring next digit (2) of the dividend behind the 195 and repeat the process: 1952 / 321

Let's proceed to step 4:
When dividing 1952 by 321, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 1926 away from 1952, we end up with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 321

Advancing to step 5:
267 divided by 321 is 0 with a remainder of 267.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we take 0 away from 267, we end up with 267.
Bring next digit (8) of the dividend behind the 267 and repeat the process: 2678 / 321

Moving on to step 6:
When dividing 2678 by 321, we get 8 with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 1608.0
If we take 2568 away from 2678, we end up with 110.
Bring next digit (5) of the dividend behind the 110 and repeat the process: 1105 / 321

Going ahead to step 7:
321 goes into 1105 3 times with a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 16083.0
If we take 963 away from 1105, we end up with 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 321

Step 8:
If we divide 1429 by 321, we get 4 and a remainder of 145.
Write down 4 as next digit of the result. 
Result so far: 160834.0
If we subtract 1284 from 1429, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
321 goes into 1450 4 times with a remainder of 166.
The next digit of our result is 4. 
Result so far: 160834.4
The remainder is 166 after subtracting 1284 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 10:
321 can be fit into 1660 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 160834.45
The remainder is 55 after subtracting 1605 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 321, we get 1 with a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 160834.451
The remainder is 229 after subtracting 321 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 12:
The number 321 fits into 2290 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 160834.4517
If we take 2247 away from 2290, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
When dividing 430 by 321, we get 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 160834.45171
Subtracting 321 from 430 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 14:
1090 divided by 321 is 3 with a remainder of 127.
The next digit of our result is 3. 
Result so far: 160834.451713
Deduct 963 from 1090 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 15:
321 can be fit into 1270 3 times, resulting in a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 160834.4517133
The remainder is 307 after subtracting 963 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The final outcome is 160834.4517133, with a leftover of 3.07e-06.
