We look at the division of 45985949 by 316 
Let's see how many times 316 fits into 45985949.

On to step 1:
316 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 316

Advancing to step 2:
When dividing 45 by 316, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 316

Going ahead to step 3:
316 goes into 459 1 times with a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 316 away from 459, we end up with 143.
Append the next digit (8) from the dividend to 143 and continue with: 1438 / 316

Step 4:
1438 divided by 316 is 4 with a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1264 from 1438 to get 174.
Fetch the next digit (5) from the dividend, attach it to 174 and continue: 1745 / 316

On to step 5:
When dividing 1745 by 316, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
If we subtract 1580 from 1745, we get 165.
Append the next digit (9) from the dividend to 165 and continue with: 1659 / 316

Advancing to step 6:
When dividing 1659 by 316, we get 5 with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 1455.0
If we take 1580 away from 1659, we end up with 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 316

On to step 7:
316 can be fit into 794 2 times, resulting in a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 14552.0
If we take 632 away from 794, we end up with 162.
Include the next digit (9) from the dividend after 162, then repeat: 1629 / 316

Advancing to step 8:
The number 316 fits into 1629 5 times, leaving a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 145525.0
Subtract 1580 from 1629 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
The number 316 fits into 490 1 times, leaving a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 145525.1
Subtract 316 from 490 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
When dividing 1740 by 316, we get 5 with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 145525.15
The remainder is 160 after subtracting 1580 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
When dividing 1600 by 316, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 145525.155
The remainder is 20 after subtracting 1580 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 145525.155, and the remainder is 0.002.
