We're dividing 49271942 by 172 
We want to figure out the number of times 49271942 can be divided by 172.

Advancing to step 1:
If we divide 4 by 172, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 172

Advancing to step 2:
49 divided by 172 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 172

On to step 3:
172 can be fit into 492 2 times, resulting in a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 148 after subtracting 344 from 492.
Take the next digit (7) from the dividend and append it to 148, then repeat: 1487 / 172

Going ahead to step 4:
1487 divided by 172 is 8 with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 1376 from 1487, we get 111.
Fetch the next digit (1) from the dividend, attach it to 111 and continue: 1111 / 172

Going ahead to step 5:
172 can be fit into 1111 6 times, resulting in a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
The remainder is 79 after subtracting 1032 from 1111.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 172

Moving on to step 6:
When dividing 799 by 172, we get 4 with a remainder of 111.
Put 4 as the next digit of the answer. 
Result so far: 2864.0
Subtracting 688 from 799 leaves us with 111.
Include the next digit (4) from the dividend after 111, then repeat: 1114 / 172

Advancing to step 7:
The number 172 fits into 1114 6 times, leaving a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 28646.0
Subtract 1032 from 1114 to get 82.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 172

Step 8:
172 can be fit into 822 4 times, resulting in a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 286464.0
Subtract 688 from 822 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
1340 divided by 172 is 7 with a remainder of 136.
Put 7 as the next digit of the answer. 
Result so far: 286464.7
The remainder is 136 after subtracting 1204 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
When dividing 1360 by 172, we get 7 with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 286464.77
If we subtract 1204 from 1360, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The quotient of the division is 286464.77, and the remainder is 0.156.
