We're dividing 172112 by 49 
We want to divide 172112 by 49.

Step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 49

Let's proceed to step 2:
When dividing 17 by 49, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 49

Advancing to step 3:
49 goes into 172 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 147 from 172, we get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 49

Advancing to step 4:
251 divided by 49 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 245 from 251, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 49

Advancing to step 5:
49 can be fit into 61 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 351.0
Subtracting 49 from 61 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 49

Moving on to step 6:
49 goes into 122 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3512.0
If we take 98 away from 122, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
The number 49 fits into 240 4 times, leaving a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 3512.4
Subtracting 196 from 240 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
When dividing 440 by 49, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 3512.48
If we subtract 392 from 440, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
If we divide 480 by 49, we get 9 and a remainder of 39.
The next digit of our result is 9. 
Result so far: 3512.489
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
When dividing 390 by 49, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 3512.4897
Subtracting 343 from 390 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
If we divide 470 by 49, we get 9 and a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 3512.48979
Subtracting 441 from 470 leaves us with 29.
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 12:
If we divide 290 by 49, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 3512.489795
Deduct 245 from 290 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
49 goes into 450 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 3512.4897959
Subtracting 441 from 450 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
49 can be fit into 90 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 3512.48979591
Subtracting 49 from 90 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 3512.48979591 with a remaining 4.1e-08.
