We divide 21870207 by 437
We want to divide 21870207 by 437.

On to step 1:
The number 437 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 437

Let's proceed to step 2:
If we divide 21 by 437, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 437

Let's proceed to step 3:
When dividing 218 by 437, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Bring next digit (7) of the dividend behind the 218 and repeat the process: 2187 / 437

Let's proceed to step 4:
2187 divided by 437 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2185 from 2187 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 437

Advancing to step 5:
The number 437 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 437

Advancing to step 6:
If we divide 202 by 437, we get 0 and a remainder of 202.
The next digit of our result is 0. 
Result so far: 500.0
Subtracting 0 from 202 leaves us with 202.
Take the next digit (0) from the dividend and append it to 202, then repeat: 2020 / 437

Moving on to step 7:
437 goes into 2020 4 times with a remainder of 272.
The next digit of our result is 4. 
Result so far: 5004.0
Subtracting 1748 from 2020 leaves us with 272.
Take the next digit (7) from the dividend and append it to 272, then repeat: 2727 / 437

Going ahead to step 8:
437 can be fit into 2727 6 times, resulting in a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 50046.0
The remainder is 105 after subtracting 2622 from 2727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
437 goes into 1050 2 times with a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 50046.2
The remainder is 176 after subtracting 874 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
437 can be fit into 1760 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 50046.24
Subtract 1748 from 1760 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 437 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 50046.24
The remainder is 120 after subtracting 0 from 120.
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 12:
When dividing 1200 by 437, we get 2 with a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 50046.2402
If we take 874 away from 1200, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 13:
3260 divided by 437 is 7 with a remainder of 201.
Put 7 as the next digit of the answer. 
Result so far: 50046.24027
Subtracting 3059 from 3260 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 14:
When dividing 2010 by 437, we get 4 with a remainder of 262.
The number 4 becomes the next digit in our result. 
Result so far: 50046.240274
Deduct 1748 from 2010 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 15:
437 goes into 2620 5 times with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 50046.2402745
Deduct 2185 from 2620 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 16:
437 can be fit into 4350 9 times, resulting in a remainder of 417.
Record the quotient 9 as the next digit in the result. 
Result so far: 50046.24027459
If we subtract 3933 from 4350, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

After the division, we end up with 50046.24027459 and a remainder of 4.17e-07.
