We're dividing 21191428 by 376 
Let's see how many times 376 fits into 21191428.

Moving on to step 1:
2 divided by 376 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 376

Advancing to step 2:
376 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 376

Let's proceed to step 3:
376 goes into 211 0 times with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Fetch the next digit (9) from the dividend, attach it to 211 and continue: 2119 / 376

Step 4:
376 goes into 2119 5 times with a remainder of 239.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1880 from 2119 to get 239.
Include the next digit (1) from the dividend after 239, then repeat: 2391 / 376

Moving on to step 5:
376 can be fit into 2391 6 times, resulting in a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 2256 from 2391, we get 135.
Fetch the next digit (4) from the dividend, attach it to 135 and continue: 1354 / 376

Step 6:
376 can be fit into 1354 3 times, resulting in a remainder of 226.
The next digit of our result is 3. 
Result so far: 563.0
If we subtract 1128 from 1354, we get 226.
Grab the next digit (2) from the dividend, add it to 226, then carry on: 2262 / 376

On to step 7:
2262 divided by 376 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 5636.0
Deduct 2256 from 2262 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 376

On to step 8:
376 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 56360.0
Subtract 0 from 68 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
376 goes into 680 1 times with a remainder of 304.
Put 1 as the next digit of the answer. 
Result so far: 56360.1
Subtract 376 from 680 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 10:
The number 376 fits into 3040 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 56360.18
If we take 3008 away from 3040, we end up 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.

Moving on to step 11:
376 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 56360.18
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
3200 divided by 376 is 8 with a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 56360.1808
If we subtract 3008 from 3200, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 13:
The number 376 fits into 1920 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 56360.18085
Subtract 1880 from 1920 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
376 goes into 400 1 times with a remainder of 24.
The next digit of our result is 1. 
Result so far: 56360.180851
Deduct 376 from 400 and we're left 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.

Going ahead to step 15:
If we divide 240 by 376, we get 0 and a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 56360.180851
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
376 can be fit into 2400 6 times, resulting in a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 56360.18085106
Subtracting 2256 from 2400 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 56360.18085106, with a leftover of 1.44e-07.
