Let's divide 18737436 by 813
We want to divide 18737436 by 813.

Going ahead to step 1:
When dividing 1 by 813, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 813

On to step 2:
813 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 813

On to step 3:
When dividing 187 by 813, we get 0 with a remainder of 187.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 187 after subtracting 0 from 187.
Fetch the next digit (3) from the dividend, attach it to 187 and continue: 1873 / 813

Moving on to step 4:
813 goes into 1873 2 times with a remainder of 247.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1626 from 1873 leaves us with 247.
Take the next digit (7) from the dividend and append it to 247, then repeat: 2477 / 813

Step 5:
The number 813 fits into 2477 3 times, leaving a remainder of 38.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 38 after subtracting 2439 from 2477.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 813

Going ahead to step 6:
813 can be fit into 384 0 times, resulting in a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Deduct 0 from 384 and we're left with 384.
Include the next digit (3) from the dividend after 384, then repeat: 3843 / 813

Moving on to step 7:
The number 813 fits into 3843 4 times, leaving a remainder of 591.
The number 4 becomes the next digit in our result. 
Result so far: 2304.0
Deduct 3252 from 3843 and we're left with 591.
Bring next digit (6) of the dividend behind the 591 and repeat the process: 5916 / 813

Going ahead to step 8:
When dividing 5916 by 813, we get 7 with a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 23047.0
Subtract 5691 from 5916 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
The number 813 fits into 2250 2 times, leaving a remainder of 624.
Record the quotient 2 as the next digit in the result. 
Result so far: 23047.2
The remainder is 624 after subtracting 1626 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 10:
When dividing 6240 by 813, we get 7 with a remainder of 549.
The next digit of our result is 7. 
Result so far: 23047.27
Deduct 5691 from 6240 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 11:
If we divide 5490 by 813, we get 6 and a remainder of 612.
Use 6 as the next digit of our solution. 
Result so far: 23047.276
The remainder is 612 after subtracting 4878 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 12:
813 can be fit into 6120 7 times, resulting in a remainder of 429.
Put 7 as the next digit of the answer. 
Result so far: 23047.2767
Subtract 5691 from 6120 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 13:
813 can be fit into 4290 5 times, resulting in a remainder of 225.
The next digit of our result is 5. 
Result so far: 23047.27675
Subtracting 4065 from 4290 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 14:
If we divide 2250 by 813, we get 2 and a remainder of 624.
Write down 2 as next digit of the result. 
Result so far: 23047.276752
If we take 1626 away from 2250, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 15:
6240 divided by 813 is 7 with a remainder of 549.
Record the quotient 7 as the next digit in the result. 
Result so far: 23047.2767527
Deduct 5691 from 6240 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 16:
813 goes into 5490 6 times with a remainder of 612.
The next digit of our result is 6. 
Result so far: 23047.27675276
Deduct 4878 from 5490 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The quotient of the division is 23047.27675276, and the remainder is 6.12e-07.
