67851989 divided by 28 
We're looking to find how many times 28 goes into 67851989.

Moving on to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 28

On to step 2:
67 divided by 28 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 56 from 67 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 28

Step 3:
28 can be fit into 118 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 112 from 118 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 28

Moving on to step 4:
If we divide 65 by 28, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 242.0
If we take 56 away from 65, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 28

Step 5:
28 can be fit into 91 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 2423.0
Subtracting 84 from 91 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 28

On to step 6:
28 goes into 79 2 times with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 24232.0
Subtract 56 from 79 to get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 28

Step 7:
238 divided by 28 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 242328.0
If we take 224 away from 238, we end up with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 28

Advancing to step 8:
28 goes into 149 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 2423285.0
If we subtract 140 from 149, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
90 divided by 28 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 2423285.3
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 28, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2423285.32
Subtracting 56 from 60 leaves us 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.

Advancing to step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 2423285.321
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.

Advancing to step 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2423285.3214
If we take 112 away from 120, 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.

Let's proceed to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2423285.32142
If we take 56 away from 80, 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.

Moving on to step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 2423285.321428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2423285.3214285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 2423285.32142857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 2423285.32142857, and the remainder is 4e-09.
