Let's divide 30912149 by 417
We want to divide 30912149 by 417.

Going ahead to step 1:
3 divided by 417 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 417

On to step 2:
30 divided by 417 is 0 with 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 (9) from the dividend, add it to 30, then carry on: 309 / 417

Going ahead to step 3:
309 divided by 417 is 0 with a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Include the next digit (1) from the dividend after 309, then repeat: 3091 / 417

Going ahead to step 4:
The number 417 fits into 3091 7 times, leaving a remainder of 172.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2919 from 3091 and we're left with 172.
Append the next digit (2) from the dividend to 172 and continue with: 1722 / 417

On to step 5:
417 can be fit into 1722 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 1668 from 1722 to get 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 417

Moving on to step 6:
417 goes into 541 1 times with a remainder of 124.
The next digit of our result is 1. 
Result so far: 741.0
If we subtract 417 from 541, we get 124.
Grab the next digit (4) from the dividend, add it to 124, then carry on: 1244 / 417

Going ahead to step 7:
When dividing 1244 by 417, we get 2 with a remainder of 410.
The number 2 becomes the next digit in our result. 
Result so far: 7412.0
The remainder is 410 after subtracting 834 from 1244.
Append the next digit (9) from the dividend to 410 and continue with: 4109 / 417

On to step 8:
4109 divided by 417 is 9 with a remainder of 356.
Put 9 as the next digit of the answer. 
Result so far: 74129.0
The remainder is 356 after subtracting 3753 from 4109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 9:
417 goes into 3560 8 times with a remainder of 224.
The next digit of our result is 8. 
Result so far: 74129.8
The remainder is 224 after subtracting 3336 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
When dividing 2240 by 417, we get 5 with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 74129.85
If we subtract 2085 from 2240, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 11:
1550 divided by 417 is 3 with a remainder of 299.
Use 3 as the next digit of our solution. 
Result so far: 74129.853
If we take 1251 away from 1550, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 12:
If we divide 2990 by 417, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 74129.8537
Subtract 2919 from 2990 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 13:
417 goes into 710 1 times with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 74129.85371
Subtract 417 from 710 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 14:
The number 417 fits into 2930 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 74129.853717
Subtract 2919 from 2930 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 15:
If we divide 110 by 417, we get 0 and a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 74129.853717
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
If we divide 1100 by 417, we get 2 and a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 74129.85371702
If we subtract 834 from 1100, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final result is 74129.85371702 with a remainder of 2.66e-07.
