We divide 51321342 by 507
Let's see how many times 507 fits into 51321342.

Moving on to step 1:
507 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 507

Advancing to step 2:
If we divide 51 by 507, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 507

Step 3:
513 divided by 507 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 507 away from 513, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 507

Going ahead to step 4:
62 divided by 507 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 62 to get 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 507

Let's proceed to step 5:
The number 507 fits into 621 1 times, leaving a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 101.0
Deduct 507 from 621 and we're left with 114.
Fetch the next digit (3) from the dividend, attach it to 114 and continue: 1143 / 507

Advancing to step 6:
The number 507 fits into 1143 2 times, leaving a remainder of 129.
Record the quotient 2 as the next digit in the result. 
Result so far: 1012.0
If we subtract 1014 from 1143, we get 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 507

On to step 7:
1294 divided by 507 is 2 with a remainder of 280.
The number 2 becomes the next digit in our result. 
Result so far: 10122.0
Subtract 1014 from 1294 to get 280.
Grab the next digit (2) from the dividend, add it to 280, then carry on: 2802 / 507

Advancing to step 8:
If we divide 2802 by 507, we get 5 and a remainder of 267.
Put 5 as the next digit of the answer. 
Result so far: 101225.0
Deduct 2535 from 2802 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
507 can be fit into 2670 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 101225.5
If we subtract 2535 from 2670, we 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 10:
507 can be fit into 1350 2 times, resulting in a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 101225.52
Deduct 1014 from 1350 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 11:
When dividing 3360 by 507, we get 6 with a remainder of 318.
Use 6 as the next digit of our solution. 
Result so far: 101225.526
If we subtract 3042 from 3360, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 12:
507 goes into 3180 6 times with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 101225.5266
Subtracting 3042 from 3180 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 101225.5266 with a remainder of 0.00138.
