109789 divided by 51 
Our goal is to divide 109789 by 51.

Let's proceed to step 1:
51 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 51

Advancing to step 2:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 51

Going ahead to step 3:
If we divide 109 by 51, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 102 from 109 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 51

Let's proceed to step 4:
The number 51 fits into 77 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 51 from 77, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 51

Going ahead to step 5:
268 divided by 51 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Deduct 255 from 268 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 51

Moving on to step 6:
139 divided by 51 is 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2152.0
If we subtract 102 from 139, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
370 divided by 51 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2152.7
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2152.72
If we take 102 away from 130, 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 9:
280 divided by 51 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2152.725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 2152.7254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2152.72549
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
When dividing 10 by 51, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2152.72549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
51 goes into 100 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 2152.7254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 2152.72549019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 2152.72549019 with a balance of 3.1e-08.
