21376089 divided by 375 
We want to divide 21376089 by 375.

Step 1:
When dividing 2 by 375, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 375

Advancing to step 2:
If we divide 21 by 375, we get 0 and 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.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 375

Advancing to step 3:
When dividing 213 by 375, we get 0 with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Bring next digit (7) of the dividend behind the 213 and repeat the process: 2137 / 375

Going ahead to step 4:
375 goes into 2137 5 times with a remainder of 262.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 1875 from 2137 leaves us with 262.
Bring next digit (6) of the dividend behind the 262 and repeat the process: 2626 / 375

Going ahead to step 5:
The number 375 fits into 2626 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 2625 from 2626 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 375

Advancing to step 6:
If we divide 10 by 375, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 570.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 375

Step 7:
375 goes into 108 0 times with a remainder of 108.
Record the quotient 0 as the next digit in the result. 
Result so far: 5700.0
If we take 0 away from 108, we end up with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 375

Step 8:
1089 divided by 375 is 2 with a remainder of 339.
The number 2 becomes the next digit in our result. 
Result so far: 57002.0
The remainder is 339 after subtracting 750 from 1089.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 9:
When dividing 3390 by 375, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 57002.9
Subtract 3375 from 3390 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
375 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 57002.9
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
If we divide 1500 by 375, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 57002.904
Deduct 1500 from 1500 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
375 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 57002.904
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
0 divided by 375 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 57002.904
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 57002.904, with a leftover of 0.0.
