Let's divide 21753237 by 402
Let's see how many times 402 fits into 21753237.

On to step 1:
2 divided by 402 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 402

Let's proceed to step 2:
When dividing 21 by 402, we get 0 with 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 (7) from the dividend after 21, then repeat: 217 / 402

On to step 3:
If we divide 217 by 402, we get 0 and a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 402

Moving on to step 4:
402 can be fit into 2175 5 times, resulting in a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 165 after subtracting 2010 from 2175.
Append the next digit (3) from the dividend to 165 and continue with: 1653 / 402

Going ahead to step 5:
402 goes into 1653 4 times with a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 1608 from 1653, we get 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 402

Step 6:
The number 402 fits into 452 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 541.0
Subtracting 402 from 452 leaves us with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 402

Step 7:
The number 402 fits into 503 1 times, leaving a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 5411.0
If we take 402 away from 503, we end up with 101.
Append the next digit (7) from the dividend to 101 and continue with: 1017 / 402

On to step 8:
When dividing 1017 by 402, we get 2 with a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 54112.0
The remainder is 213 after subtracting 804 from 1017.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 9:
2130 divided by 402 is 5 with a remainder of 120.
The next digit of our result is 5. 
Result so far: 54112.5
The remainder is 120 after subtracting 2010 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
When dividing 1200 by 402, we get 2 with a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 54112.52
Subtracting 804 from 1200 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
402 goes into 3960 9 times with a remainder of 342.
Put 9 as the next digit of the answer. 
Result so far: 54112.529
Deduct 3618 from 3960 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 12:
3420 divided by 402 is 8 with a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 54112.5298
If we take 3216 away from 3420, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 13:
402 can be fit into 2040 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 54112.52985
Subtract 2010 from 2040 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
When dividing 300 by 402, we get 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 54112.52985
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
When dividing 3000 by 402, we get 7 with a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 54112.5298507
If we subtract 2814 from 3000, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 16:
If we divide 1860 by 402, we get 4 and a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 54112.52985074
Deduct 1608 from 1860 and we're left 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.

Our division results in 54112.52985074 with a remaining 2.52e-07.
