We look at the division of 30994948 by 453 
We want to divide 30994948 by 453.

Moving on to step 1:
3 divided by 453 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 453

Let's proceed to step 2:
453 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 453

Moving on to step 3:
If we divide 309 by 453, we get 0 and a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 309 to get 309.
Include the next digit (9) from the dividend after 309, then repeat: 3099 / 453

Moving on to step 4:
453 can be fit into 3099 6 times, resulting in a remainder of 381.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2718 from 3099 to get 381.
Grab the next digit (4) from the dividend, add it to 381, then carry on: 3814 / 453

Advancing to step 5:
If we divide 3814 by 453, we get 8 and a remainder of 190.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 190 after subtracting 3624 from 3814.
Include the next digit (9) from the dividend after 190, then repeat: 1909 / 453

Step 6:
453 goes into 1909 4 times with a remainder of 97.
The next digit of our result is 4. 
Result so far: 684.0
If we subtract 1812 from 1909, we get 97.
Fetch the next digit (4) from the dividend, attach it to 97 and continue: 974 / 453

Advancing to step 7:
The number 453 fits into 974 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 6842.0
If we subtract 906 from 974, we get 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 453

Moving on to step 8:
453 can be fit into 688 1 times, resulting in a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 68421.0
The remainder is 235 after subtracting 453 from 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 9:
453 can be fit into 2350 5 times, resulting in a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 68421.5
If we take 2265 away from 2350, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
850 divided by 453 is 1 with a remainder of 397.
The next digit of our result is 1. 
Result so far: 68421.51
The remainder is 397 after subtracting 453 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 11:
453 goes into 3970 8 times with a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 68421.518
Subtracting 3624 from 3970 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 12:
3460 divided by 453 is 7 with a remainder of 289.
The next digit of our result is 7. 
Result so far: 68421.5187
The remainder is 289 after subtracting 3171 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 13:
If we divide 2890 by 453, we get 6 and a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 68421.51876
If we subtract 2718 from 2890, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 14:
453 can be fit into 1720 3 times, resulting in a remainder of 361.
Use 3 as the next digit of our solution. 
Result so far: 68421.518763
If we take 1359 away from 1720, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 15:
3610 divided by 453 is 7 with a remainder of 439.
The next digit of our result is 7. 
Result so far: 68421.5187637
The remainder is 439 after subtracting 3171 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 16:
If we divide 4390 by 453, we get 9 and a remainder of 313.
The number 9 becomes the next digit in our result. 
Result so far: 68421.51876379
Deduct 4077 from 4390 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The final outcome is 68421.51876379, with a leftover of 3.13e-07.
