71628914 ÷ 172 
Let's see how many times 172 fits into 71628914.

Going ahead to step 1:
The number 172 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 172

On to step 2:
172 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 172

Let's proceed to step 3:
When dividing 716 by 172, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 688 from 716 to get 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 172

Let's proceed to step 4:
When dividing 282 by 172, we get 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 172 from 282 to get 110.
Bring next digit (8) of the dividend behind the 110 and repeat the process: 1108 / 172

Going ahead to step 5:
If we divide 1108 by 172, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 416.0
Subtract 1032 from 1108 to get 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 172

Going ahead to step 6:
172 goes into 769 4 times with a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 4164.0
Subtract 688 from 769 to get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 172

Advancing to step 7:
172 can be fit into 811 4 times, resulting in a remainder of 123.
The number 4 becomes the next digit in our result. 
Result so far: 41644.0
If we take 688 away from 811, we end up with 123.
Fetch the next digit (4) from the dividend, attach it to 123 and continue: 1234 / 172

Advancing to step 8:
When dividing 1234 by 172, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 416447.0
If we subtract 1204 from 1234, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
172 goes into 300 1 times with a remainder of 128.
Record the quotient 1 as the next digit in the result. 
Result so far: 416447.1
The remainder is 128 after subtracting 172 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
The number 172 fits into 1280 7 times, leaving a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 416447.17
If we take 1204 away from 1280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
760 divided by 172 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 416447.174
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
172 goes into 720 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 416447.1744
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 416447.1744, with a leftover of 0.00032.
