We look at the division of 21386272 by 372 
We want to figure out the number of times 21386272 can be divided by 372.

Going ahead to step 1:
2 divided by 372 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 372

On to step 2:
372 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 372

Moving on to step 3:
When dividing 213 by 372, we get 0 with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Append the next digit (8) from the dividend to 213 and continue with: 2138 / 372

Going ahead to step 4:
372 can be fit into 2138 5 times, resulting in a remainder of 278.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 1860 from 2138 to get 278.
Bring next digit (6) of the dividend behind the 278 and repeat the process: 2786 / 372

Moving on to step 5:
When dividing 2786 by 372, we get 7 with a remainder of 182.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 182 after subtracting 2604 from 2786.
Bring next digit (2) of the dividend behind the 182 and repeat the process: 1822 / 372

Going ahead to step 6:
372 goes into 1822 4 times with a remainder of 334.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
The remainder is 334 after subtracting 1488 from 1822.
Take the next digit (7) from the dividend and append it to 334, then repeat: 3347 / 372

Step 7:
The number 372 fits into 3347 8 times, leaving a remainder of 371.
Record the quotient 8 as the next digit in the result. 
Result so far: 5748.0
Subtract 2976 from 3347 to get 371.
Take the next digit (2) from the dividend and append it to 371, then repeat: 3712 / 372

Going ahead to step 8:
If we divide 3712 by 372, we get 9 and a remainder of 364.
The number 9 becomes the next digit in our result. 
Result so far: 57489.0
The remainder is 364 after subtracting 3348 from 3712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 9:
The number 372 fits into 3640 9 times, leaving a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 57489.9
Subtracting 3348 from 3640 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 10:
When dividing 2920 by 372, we get 7 with a remainder of 316.
Use 7 as the next digit of our solution. 
Result so far: 57489.97
If we subtract 2604 from 2920, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 11:
372 can be fit into 3160 8 times, resulting in a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 57489.978
The remainder is 184 after subtracting 2976 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
1840 divided by 372 is 4 with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 57489.9784
The remainder is 352 after subtracting 1488 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 13:
3520 divided by 372 is 9 with a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 57489.97849
Subtract 3348 from 3520 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 14:
The number 372 fits into 1720 4 times, leaving a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 57489.978494
Subtract 1488 from 1720 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 15:
372 goes into 2320 6 times with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 57489.9784946
If we take 2232 away from 2320, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
372 goes into 880 2 times with a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 57489.97849462
Deduct 744 from 880 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 57489.97849462, with a leftover of 1.36e-07.
