Let's divide 31916889 by 28
We want to figure out the number of times 31916889 can be divided by 28.

On to step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 28

Advancing to step 2:
The number 28 fits into 31 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 28 from 31, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 28

Going ahead to step 3:
39 divided by 28 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 28 from 39, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 28

Moving on to step 4:
28 goes into 111 3 times with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Deduct 84 from 111 and we're left with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 28

Moving on to step 5:
28 can be fit into 276 9 times, resulting in a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 1139.0
Subtract 252 from 276 to get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 28

Advancing to step 6:
When dividing 248 by 28, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 11398.0
If we take 224 away from 248, we end up with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 28

Advancing to step 7:
The number 28 fits into 248 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 113988.0
The remainder is 24 after subtracting 224 from 248.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 28

Moving on to step 8:
28 can be fit into 249 8 times, resulting in a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 1139888.0
Deduct 224 from 249 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
The number 28 fits into 250 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 1139888.8
Subtracting 224 from 250 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
28 can be fit into 260 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 1139888.89
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1139888.892
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
When dividing 240 by 28, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1139888.8928
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1139888.89285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 1139888.892857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1139888.8928571
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 16:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1139888.89285714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1139888.89285714 with a remaining 8e-09.
