We look at the division of 57979317 by 480 
Let's see how many times 480 fits into 57979317.

Step 1:
When dividing 5 by 480, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 480

On to step 2:
The number 480 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 480

Step 3:
579 divided by 480 is 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 480 from 579 leaves us with 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 480

Going ahead to step 4:
480 goes into 997 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 960 away from 997, we end up with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 480

Going ahead to step 5:
The number 480 fits into 379 0 times, leaving a remainder of 379.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtract 0 from 379 to get 379.
Include the next digit (3) from the dividend after 379, then repeat: 3793 / 480

Let's proceed to step 6:
480 goes into 3793 7 times with a remainder of 433.
The number 7 becomes the next digit in our result. 
Result so far: 1207.0
Deduct 3360 from 3793 and we're left with 433.
Append the next digit (1) from the dividend to 433 and continue with: 4331 / 480

Advancing to step 7:
If we divide 4331 by 480, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 12079.0
If we take 4320 away from 4331, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 480

Moving on to step 8:
If we divide 117 by 480, we get 0 and a remainder of 117.
Write down 0 as next digit of the result. 
Result so far: 120790.0
Subtract 0 from 117 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
480 can be fit into 1170 2 times, resulting in a remainder of 210.
The number 2 becomes the next digit in our result. 
Result so far: 120790.2
If we take 960 away from 1170, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
2100 divided by 480 is 4 with a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 120790.24
Deduct 1920 from 2100 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
1800 divided by 480 is 3 with a remainder of 360.
Record the quotient 3 as the next digit in the result. 
Result so far: 120790.243
Deduct 1440 from 1800 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
480 can be fit into 3600 7 times, resulting in a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 120790.2437
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
If we divide 2400 by 480, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 120790.24375
If we take 2400 away from 2400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
The number 480 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120790.24375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
The number 480 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120790.24375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 120790.24375 with a remainder of 0.0.
