We divide 51338637 by 507
We want to figure out the number of times 51338637 can be divided by 507.

On to step 1:
The number 507 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 507

Let's proceed to step 2:
The number 507 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 507

Step 3:
If we divide 513 by 507, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 507 from 513.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 507

Advancing to step 4:
The number 507 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 63, we get 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 507

Let's proceed to step 5:
If we divide 638 by 507, we get 1 and a remainder of 131.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 131 after subtracting 507 from 638.
Take the next digit (6) from the dividend and append it to 131, then repeat: 1316 / 507

Let's proceed to step 6:
If we divide 1316 by 507, we get 2 and a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 1012.0
Deduct 1014 from 1316 and we're left with 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 507

On to step 7:
If we divide 3023 by 507, we get 5 and a remainder of 488.
Use 5 as the next digit of our solution. 
Result so far: 10125.0
Deduct 2535 from 3023 and we're left with 488.
Grab the next digit (7) from the dividend, add it to 488, then carry on: 4887 / 507

Let's proceed to step 8:
507 goes into 4887 9 times with a remainder of 324.
Write down 9 as next digit of the result. 
Result so far: 101259.0
If we take 4563 away from 4887, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
The number 507 fits into 3240 6 times, leaving a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 101259.6
Subtracting 3042 from 3240 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
1980 divided by 507 is 3 with a remainder of 459.
Write down 3 as next digit of the result. 
Result so far: 101259.63
If we subtract 1521 from 1980, we get 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Advancing to step 11:
4590 divided by 507 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 101259.639
The remainder is 27 after subtracting 4563 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
The number 507 fits into 270 0 times, leaving a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 101259.639
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 13:
2700 divided by 507 is 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 101259.63905
Subtract 2535 from 2700 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 14:
1650 divided by 507 is 3 with a remainder of 129.
The next digit of our result is 3. 
Result so far: 101259.639053
Subtract 1521 from 1650 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 15:
The number 507 fits into 1290 2 times, leaving a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 101259.6390532
Subtract 1014 from 1290 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 16:
507 can be fit into 2760 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 101259.63905325
Subtracting 2535 from 2760 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 101259.63905325 with a remainder of 2.25e-07.
