We look at the division of 81990 by 56 
Let's see how many times 56 fits into 81990.

Moving on to step 1:
When dividing 8 by 56, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 56

Advancing to step 2:
When dividing 81 by 56, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 56 from 81, we get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 56

On to step 3:
When dividing 259 by 56, we get 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 224 from 259 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 56

Going ahead to step 4:
56 goes into 359 6 times with a remainder of 23.
The next digit of our result is 6. 
Result so far: 146.0
Subtracting 336 from 359 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 56

Moving on to step 5:
When dividing 230 by 56, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 1464.0
Subtract 224 from 230 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
56 goes into 60 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1464.1
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.

Let's proceed to step 7:
If we divide 40 by 56, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1464.1
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 56 fits into 400 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 1464.107
Deduct 392 from 400 and we're left 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.

Going ahead to step 9:
When dividing 80 by 56, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1464.1071
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.

Advancing to step 10:
If we divide 240 by 56, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1464.10714
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.

Moving on to step 11:
If we divide 160 by 56, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1464.107142
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
The number 56 fits into 480 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1464.1071428
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
When dividing 320 by 56, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1464.10714285
Deduct 280 from 320 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 1464.10714285 and a remainder of 4e-08.
