We're dividing 5121380 by 757 
We're looking to find how many times 757 goes into 5121380.

Step 1:
The number 757 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
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 / 757

Moving on to step 2:
When dividing 51 by 757, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 757

Advancing to step 3:
If we divide 512 by 757, we get 0 and a remainder of 512.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 512, we get 512.
Take the next digit (1) from the dividend and append it to 512, then repeat: 5121 / 757

Moving on to step 4:
5121 divided by 757 is 6 with a remainder of 579.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4542 from 5121 and we're left with 579.
Include the next digit (3) from the dividend after 579, then repeat: 5793 / 757

Let's proceed to step 5:
If we divide 5793 by 757, we get 7 and a remainder of 494.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 5299 from 5793 leaves us with 494.
Fetch the next digit (8) from the dividend, attach it to 494 and continue: 4948 / 757

Step 6:
If we divide 4948 by 757, we get 6 and a remainder of 406.
Use 6 as the next digit of our solution. 
Result so far: 676.0
If we take 4542 away from 4948, we end up with 406.
Bring next digit (0) of the dividend behind the 406 and repeat the process: 4060 / 757

Moving on to step 7:
757 goes into 4060 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 6765.0
Deduct 3785 from 4060 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 8:
If we divide 2750 by 757, we get 3 and a remainder of 479.
Put 3 as the next digit of the answer. 
Result so far: 6765.3
Subtract 2271 from 2750 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
757 can be fit into 4790 6 times, resulting in a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 6765.36
Subtracting 4542 from 4790 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 10:
When dividing 2480 by 757, we get 3 with a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 6765.363
Deduct 2271 from 2480 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 11:
757 can be fit into 2090 2 times, resulting in a remainder of 576.
Write down 2 as next digit of the result. 
Result so far: 6765.3632
Subtracting 1514 from 2090 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 12:
5760 divided by 757 is 7 with a remainder of 461.
Put 7 as the next digit of the answer. 
Result so far: 6765.36327
If we subtract 5299 from 5760, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 13:
757 can be fit into 4610 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 6765.363276
Subtract 4542 from 4610 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
When dividing 680 by 757, we get 0 with a remainder of 680.
The next digit of our result is 0. 
Result so far: 6765.363276
The remainder is 680 after subtracting 0 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 15:
When dividing 6800 by 757, we get 8 with a remainder of 744.
Record the quotient 8 as the next digit in the result. 
Result so far: 6765.36327608
Deduct 6056 from 6800 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final result is 6765.36327608 with a remainder of 7.44e-07.
