51972683 ÷ 491 
We're looking to find how many times 491 goes into 51972683.

Step 1:
If we divide 5 by 491, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 491

On to step 2:
491 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 491

Going ahead to step 3:
519 divided by 491 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 491 from 519 leaves us with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 491

Moving on to step 4:
The number 491 fits into 287 0 times, leaving a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 287, we get 287.
Take the next digit (2) from the dividend and append it to 287, then repeat: 2872 / 491

On to step 5:
The number 491 fits into 2872 5 times, leaving a remainder of 417.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtract 2455 from 2872 to get 417.
Grab the next digit (6) from the dividend, add it to 417, then carry on: 4176 / 491

Let's proceed to step 6:
If we divide 4176 by 491, we get 8 and a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 1058.0
Deduct 3928 from 4176 and we're left with 248.
Bring next digit (8) of the dividend behind the 248 and repeat the process: 2488 / 491

Let's proceed to step 7:
2488 divided by 491 is 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 10585.0
Subtracting 2455 from 2488 leaves us with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 491

Going ahead to step 8:
If we divide 333 by 491, we get 0 and a remainder of 333.
Record the quotient 0 as the next digit in the result. 
Result so far: 105850.0
If we take 0 away from 333, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 9:
491 goes into 3330 6 times with a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 105850.6
If we take 2946 away from 3330, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 10:
If we divide 3840 by 491, we get 7 and a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 105850.67
Deduct 3437 from 3840 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 11:
The number 491 fits into 4030 8 times, leaving a remainder of 102.
The next digit of our result is 8. 
Result so far: 105850.678
Subtracting 3928 from 4030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
The number 491 fits into 1020 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 105850.6782
If we subtract 982 from 1020, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
491 goes into 380 0 times with a remainder of 380.
The next digit of our result is 0. 
Result so far: 105850.6782
If we take 0 away from 380, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
3800 divided by 491 is 7 with a remainder of 363.
The number 7 becomes the next digit in our result. 
Result so far: 105850.678207
If we take 3437 away from 3800, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 15:
491 can be fit into 3630 7 times, resulting in a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 105850.6782077
If we take 3437 away from 3630, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

The quotient of the division is 105850.6782077, and the remainder is 1.93e-06.
