Let's divide 21781840 by 375
Our goal is to divide 21781840 by 375.

Going ahead to step 1:
When dividing 2 by 375, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 375

Moving on to step 2:
When dividing 21 by 375, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 375

Step 3:
217 divided by 375 is 0 with a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 217 leaves us with 217.
Bring next digit (8) of the dividend behind the 217 and repeat the process: 2178 / 375

Going ahead to step 4:
375 goes into 2178 5 times with a remainder of 303.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 1875 from 2178, we get 303.
Grab the next digit (1) from the dividend, add it to 303, then carry on: 3031 / 375

Advancing to step 5:
375 can be fit into 3031 8 times, resulting in a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 3000 from 3031 leaves us with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 375

On to step 6:
375 goes into 318 0 times with a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 580.0
Subtract 0 from 318 to get 318.
Bring next digit (4) of the dividend behind the 318 and repeat the process: 3184 / 375

Step 7:
375 goes into 3184 8 times with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 5808.0
The remainder is 184 after subtracting 3000 from 3184.
Append the next digit (0) from the dividend to 184 and continue with: 1840 / 375

On to step 8:
375 goes into 1840 4 times with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 58084.0
Deduct 1500 from 1840 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 9:
375 can be fit into 3400 9 times, resulting in a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 58084.9
If we take 3375 away from 3400, we end up 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.

Moving on to step 10:
250 divided by 375 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 58084.9
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 11:
2500 divided by 375 is 6 with a remainder of 250.
Use 6 as the next digit of our solution. 
Result so far: 58084.906
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
When dividing 2500 by 375, we get 6 with a remainder of 250.
The next digit of our result is 6. 
Result so far: 58084.9066
If we take 2250 away from 2500, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Our division results in 58084.9066 with a remaining 0.0025.
