We're dividing 172109 by 56 
Our goal is to divide 172109 by 56.

Moving on to step 1:
The number 56 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 56

Let's proceed to step 2:
56 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 56

Moving on to step 3:
The number 56 fits into 172 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 168 from 172, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 56

Going ahead to step 4:
If we divide 41 by 56, we get 0 and a remainder of 41.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 41, we get 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 56

Step 5:
410 divided by 56 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 307.0
The remainder is 18 after subtracting 392 from 410.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 56

Moving on to step 6:
If we divide 189 by 56, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3073.0
Deduct 168 from 189 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 56 fits into 210 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3073.3
If we take 168 away from 210, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
56 goes into 420 7 times with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 3073.37
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 56, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3073.375
Deduct 280 from 280 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
56 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3073.375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
56 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3073.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3073.375 with a remaining 0.0.
