We look at the division of 49610931 by 645 
Our goal is to divide 49610931 by 645.

Step 1:
4 divided by 645 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 645

Let's proceed to step 2:
The number 645 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 645

Moving on to step 3:
496 divided by 645 is 0 with a remainder of 496.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 496 to get 496.
Bring next digit (1) of the dividend behind the 496 and repeat the process: 4961 / 645

Moving on to step 4:
4961 divided by 645 is 7 with a remainder of 446.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4515 from 4961 leaves us with 446.
Grab the next digit (0) from the dividend, add it to 446, then carry on: 4460 / 645

Going ahead to step 5:
645 can be fit into 4460 6 times, resulting in a remainder of 590.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 3870 from 4460 leaves us with 590.
Append the next digit (9) from the dividend to 590 and continue with: 5909 / 645

Advancing to step 6:
645 goes into 5909 9 times with a remainder of 104.
Use 9 as the next digit of our solution. 
Result so far: 769.0
Subtract 5805 from 5909 to get 104.
Append the next digit (3) from the dividend to 104 and continue with: 1043 / 645

Moving on to step 7:
When dividing 1043 by 645, we get 1 with a remainder of 398.
Put 1 as the next digit of the answer. 
Result so far: 7691.0
The remainder is 398 after subtracting 645 from 1043.
Take the next digit (1) from the dividend and append it to 398, then repeat: 3981 / 645

Moving on to step 8:
645 goes into 3981 6 times with a remainder of 111.
The number 6 becomes the next digit in our result. 
Result so far: 76916.0
The remainder is 111 after subtracting 3870 from 3981.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
When dividing 1110 by 645, we get 1 with a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 76916.1
Subtract 645 from 1110 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 10:
645 can be fit into 4650 7 times, resulting in a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 76916.17
Subtract 4515 from 4650 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
When dividing 1350 by 645, we get 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 76916.172
The remainder is 60 after subtracting 1290 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
645 can be fit into 600 0 times, resulting in a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 76916.172
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
645 can be fit into 6000 9 times, resulting in a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 76916.17209
The remainder is 195 after subtracting 5805 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 14:
645 can be fit into 1950 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 76916.172093
If we subtract 1935 from 1950, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 15:
When dividing 150 by 645, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 76916.172093
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 16:
When dividing 1500 by 645, we get 2 with a remainder of 210.
Use 2 as the next digit of our solution. 
Result so far: 76916.17209302
If we take 1290 away from 1500, 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.

After the division, we end up with 76916.17209302 and a remainder of 2.1e-07.
