We're dividing 30373872 by 813 
Our goal is to divide 30373872 by 813.

Advancing to step 1:
When dividing 3 by 813, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 813

Step 2:
813 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 813

On to step 3:
813 can be fit into 303 0 times, resulting in a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 303 leaves us with 303.
Take the next digit (7) from the dividend and append it to 303, then repeat: 3037 / 813

On to step 4:
When dividing 3037 by 813, we get 3 with a remainder of 598.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2439 from 3037 and we're left with 598.
Include the next digit (3) from the dividend after 598, then repeat: 5983 / 813

Step 5:
813 goes into 5983 7 times with a remainder of 292.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 292 after subtracting 5691 from 5983.
Fetch the next digit (8) from the dividend, attach it to 292 and continue: 2928 / 813

Moving on to step 6:
The number 813 fits into 2928 3 times, leaving a remainder of 489.
The number 3 becomes the next digit in our result. 
Result so far: 373.0
If we take 2439 away from 2928, we end up with 489.
Include the next digit (7) from the dividend after 489, then repeat: 4897 / 813

On to step 7:
The number 813 fits into 4897 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 3736.0
If we subtract 4878 from 4897, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 813

Going ahead to step 8:
192 divided by 813 is 0 with a remainder of 192.
The next digit of our result is 0. 
Result so far: 37360.0
Subtracting 0 from 192 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
The number 813 fits into 1920 2 times, leaving a remainder of 294.
Record the quotient 2 as the next digit in the result. 
Result so far: 37360.2
If we subtract 1626 from 1920, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
The number 813 fits into 2940 3 times, leaving a remainder of 501.
Put 3 as the next digit of the answer. 
Result so far: 37360.23
If we subtract 2439 from 2940, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
The number 813 fits into 5010 6 times, leaving a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 37360.236
Subtracting 4878 from 5010 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
If we divide 1320 by 813, we get 1 and a remainder of 507.
Use 1 as the next digit of our solution. 
Result so far: 37360.2361
Subtract 813 from 1320 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 13:
5070 divided by 813 is 6 with a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 37360.23616
Subtracting 4878 from 5070 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
The number 813 fits into 1920 2 times, leaving a remainder of 294.
Record the quotient 2 as the next digit in the result. 
Result so far: 37360.236162
If we subtract 1626 from 1920, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 15:
813 goes into 2940 3 times with a remainder of 501.
The next digit of our result is 3. 
Result so far: 37360.2361623
Subtracting 2439 from 2940 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 16:
5010 divided by 813 is 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 37360.23616236
The remainder is 132 after subtracting 4878 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

In conclusion, the division gives 37360.23616236 with a balance of 1.32e-07.
