We're dividing 4780739 by 485 
We want to figure out the number of times 4780739 can be divided by 485.

On to step 1:
When dividing 4 by 485, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 485

Going ahead to step 2:
485 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 485

Moving on to step 3:
485 can be fit into 478 0 times, resulting in a remainder of 478.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 478 after subtracting 0 from 478.
Fetch the next digit (0) from the dividend, attach it to 478 and continue: 4780 / 485

Step 4:
The number 485 fits into 4780 9 times, leaving a remainder of 415.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 4365 from 4780 to get 415.
Grab the next digit (7) from the dividend, add it to 415, then carry on: 4157 / 485

Going ahead to step 5:
485 can be fit into 4157 8 times, resulting in a remainder of 277.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 3880 from 4157 to get 277.
Grab the next digit (3) from the dividend, add it to 277, then carry on: 2773 / 485

On to step 6:
485 can be fit into 2773 5 times, resulting in a remainder of 348.
Record the quotient 5 as the next digit in the result. 
Result so far: 985.0
If we subtract 2425 from 2773, we get 348.
Fetch the next digit (9) from the dividend, attach it to 348 and continue: 3489 / 485

Step 7:
3489 divided by 485 is 7 with a remainder of 94.
The next digit of our result is 7. 
Result so far: 9857.0
Deduct 3395 from 3489 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 8:
If we divide 940 by 485, we get 1 and a remainder of 455.
The next digit of our result is 1. 
Result so far: 9857.1
If we take 485 away from 940, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 9:
If we divide 4550 by 485, we get 9 and a remainder of 185.
Record the quotient 9 as the next digit in the result. 
Result so far: 9857.19
Subtract 4365 from 4550 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
1850 divided by 485 is 3 with a remainder of 395.
Put 3 as the next digit of the answer. 
Result so far: 9857.193
The remainder is 395 after subtracting 1455 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 11:
485 goes into 3950 8 times with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 9857.1938
If we subtract 3880 from 3950, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
When dividing 700 by 485, we get 1 with a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 9857.19381
The remainder is 215 after subtracting 485 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
If we divide 2150 by 485, we get 4 and a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 9857.193814
The remainder is 210 after subtracting 1940 from 2150.
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 14:
2100 divided by 485 is 4 with a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 9857.1938144
If we subtract 1940 from 2100, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 9857.1938144 with a remainder of 1.6e-06.
