5371343 divided by 663 
We want to divide 5371343 by 663.

Going ahead to step 1:
663 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 663

Moving on to step 2:
The number 663 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 663

Advancing to step 3:
If we divide 537 by 663, we get 0 and a remainder of 537.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 537 leaves us with 537.
Grab the next digit (1) from the dividend, add it to 537, then carry on: 5371 / 663

Advancing to step 4:
663 goes into 5371 8 times with a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5304 away from 5371, we end up with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 663

Advancing to step 5:
The number 663 fits into 673 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtract 663 from 673 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 663

Let's proceed to step 6:
The number 663 fits into 104 0 times, leaving a remainder of 104.
The next digit of our result is 0. 
Result so far: 810.0
If we take 0 away from 104, we end up with 104.
Append the next digit (3) from the dividend to 104 and continue with: 1043 / 663

Let's proceed to step 7:
663 can be fit into 1043 1 times, resulting in a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 8101.0
Deduct 663 from 1043 and we're left 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.

Step 8:
3800 divided by 663 is 5 with a remainder of 485.
Record the quotient 5 as the next digit in the result. 
Result so far: 8101.5
Subtracting 3315 from 3800 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 9:
4850 divided by 663 is 7 with a remainder of 209.
Write down 7 as next digit of the result. 
Result so far: 8101.57
Deduct 4641 from 4850 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.

Going ahead to step 10:
If we divide 2090 by 663, we get 3 and a remainder of 101.
The next digit of our result is 3. 
Result so far: 8101.573
Deduct 1989 from 2090 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 11:
When dividing 1010 by 663, we get 1 with a remainder of 347.
Record the quotient 1 as the next digit in the result. 
Result so far: 8101.5731
Deduct 663 from 1010 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 12:
3470 divided by 663 is 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 8101.57315
If we subtract 3315 from 3470, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 13:
If we divide 1550 by 663, we get 2 and a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 8101.573152
If we subtract 1326 from 1550, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 14:
663 can be fit into 2240 3 times, resulting in a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 8101.5731523
Subtract 1989 from 2240 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 15:
When dividing 2510 by 663, we get 3 with a remainder of 521.
The next digit of our result is 3. 
Result so far: 8101.57315233
The remainder is 521 after subtracting 1989 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

The final outcome is 8101.57315233, with a leftover of 5.21e-07.
