21641530 divided by 373 
We want to figure out the number of times 21641530 can be divided by 373.

Going ahead to step 1:
2 divided by 373 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 373

Going ahead to step 2:
373 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 373

Let's proceed to step 3:
373 goes into 216 0 times with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Append the next digit (4) from the dividend to 216 and continue with: 2164 / 373

Going ahead to step 4:
373 goes into 2164 5 times with a remainder of 299.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1865 from 2164, we get 299.
Grab the next digit (1) from the dividend, add it to 299, then carry on: 2991 / 373

On to step 5:
2991 divided by 373 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 58.0
Deduct 2984 from 2991 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 373

On to step 6:
When dividing 75 by 373, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 580.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 373

On to step 7:
If we divide 753 by 373, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 5802.0
Deduct 746 from 753 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 373

On to step 8:
If we divide 70 by 373, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 58020.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
373 can be fit into 700 1 times, resulting in a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 58020.1
Subtracting 373 from 700 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 10:
The number 373 fits into 3270 8 times, leaving a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 58020.18
Subtracting 2984 from 3270 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 11:
When dividing 2860 by 373, we get 7 with a remainder of 249.
The next digit of our result is 7. 
Result so far: 58020.187
Subtracting 2611 from 2860 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 12:
373 can be fit into 2490 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 58020.1876
If we take 2238 away from 2490, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 13:
2520 divided by 373 is 6 with a remainder of 282.
Record the quotient 6 as the next digit in the result. 
Result so far: 58020.18766
If we take 2238 away from 2520, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

In conclusion, the division gives 58020.18766 with a balance of 0.000282.
