30912621 divided by 49 
Our goal is to divide 30912621 by 49.

On to step 1:
49 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 49

Let's proceed to step 2:
If we divide 30 by 49, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 49

On to step 3:
309 divided by 49 is 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 294 from 309 and we're left with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 49

Step 4:
When dividing 151 by 49, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 147 from 151 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 49

Going ahead to step 5:
42 divided by 49 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
If we take 0 away from 42, we end up with 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 49

Step 6:
426 divided by 49 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 6308.0
Subtract 392 from 426 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 49

Going ahead to step 7:
When dividing 342 by 49, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 63086.0
If we subtract 294 from 342, we get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 49

On to step 8:
49 can be fit into 481 9 times, resulting in a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 630869.0
If we take 441 away from 481, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 49, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 630869.8
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 49, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 630869.81
Subtract 49 from 80 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
If we divide 310 by 49, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 630869.816
Deduct 294 from 310 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 49 fits into 160 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 630869.8163
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
When dividing 130 by 49, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 630869.81632
Deduct 98 from 130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 49 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 630869.816326
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 15:
49 can be fit into 260 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 630869.8163265
Deduct 245 from 260 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 16:
If we divide 150 by 49, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 630869.81632653
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 630869.81632653 with a remaining 3e-09.
