28631579 ÷ 172 
We want to divide 28631579 by 172.

Step 1:
172 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 172

On to step 2:
172 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 172

Moving on to step 3:
If we divide 286 by 172, we get 1 and a remainder of 114.
The next digit of our result is 1. 
Result so far: 1.0
If we take 172 away from 286, we end up with 114.
Take the next digit (3) from the dividend and append it to 114, then repeat: 1143 / 172

Moving on to step 4:
When dividing 1143 by 172, we get 6 with a remainder of 111.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 1032 from 1143 and we're left with 111.
Fetch the next digit (1) from the dividend, attach it to 111 and continue: 1111 / 172

Advancing to step 5:
172 goes into 1111 6 times with a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Subtracting 1032 from 1111 leaves us with 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 172

Going ahead to step 6:
When dividing 795 by 172, we get 4 with a remainder of 107.
Use 4 as the next digit of our solution. 
Result so far: 1664.0
The remainder is 107 after subtracting 688 from 795.
Append the next digit (7) from the dividend to 107 and continue with: 1077 / 172

Going ahead to step 7:
172 goes into 1077 6 times with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 16646.0
Subtract 1032 from 1077 to get 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 172

Let's proceed to step 8:
The number 172 fits into 459 2 times, leaving a remainder of 115.
Record the quotient 2 as the next digit in the result. 
Result so far: 166462.0
If we subtract 344 from 459, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
1150 divided by 172 is 6 with a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 166462.6
Subtract 1032 from 1150 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 10:
When dividing 1180 by 172, we get 6 with a remainder of 148.
The number 6 becomes the next digit in our result. 
Result so far: 166462.66
If we take 1032 away from 1180, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

In conclusion, the division gives 166462.66 with a balance of 0.148.
