We're dividing 78383133 by 561 
We want to divide 78383133 by 561.

On to step 1:
7 divided by 561 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 561

Step 2:
561 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 561

On to step 3:
The number 561 fits into 783 1 times, leaving a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 561 from 783 to get 222.
Take the next digit (8) from the dividend and append it to 222, then repeat: 2228 / 561

Moving on to step 4:
2228 divided by 561 is 3 with a remainder of 545.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 545 after subtracting 1683 from 2228.
Fetch the next digit (3) from the dividend, attach it to 545 and continue: 5453 / 561

Going ahead to step 5:
5453 divided by 561 is 9 with a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtract 5049 from 5453 to get 404.
Grab the next digit (1) from the dividend, add it to 404, then carry on: 4041 / 561

Moving on to step 6:
If we divide 4041 by 561, we get 7 and a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 1397.0
Deduct 3927 from 4041 and we're left with 114.
Take the next digit (3) from the dividend and append it to 114, then repeat: 1143 / 561

Let's proceed to step 7:
561 goes into 1143 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 13972.0
If we take 1122 away from 1143, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 561

Going ahead to step 8:
When dividing 213 by 561, we get 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 139720.0
If we subtract 0 from 213, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 9:
The number 561 fits into 2130 3 times, leaving a remainder of 447.
The next digit of our result is 3. 
Result so far: 139720.3
The remainder is 447 after subtracting 1683 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 10:
The number 561 fits into 4470 7 times, leaving a remainder of 543.
Record the quotient 7 as the next digit in the result. 
Result so far: 139720.37
Subtracting 3927 from 4470 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 11:
561 can be fit into 5430 9 times, resulting in a remainder of 381.
Put 9 as the next digit of the answer. 
Result so far: 139720.379
The remainder is 381 after subtracting 5049 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Going ahead to step 12:
561 goes into 3810 6 times with a remainder of 444.
Record the quotient 6 as the next digit in the result. 
Result so far: 139720.3796
The remainder is 444 after subtracting 3366 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 13:
The number 561 fits into 4440 7 times, leaving a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 139720.37967
Subtracting 3927 from 4440 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 14:
If we divide 5130 by 561, we get 9 and a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 139720.379679
If we take 5049 away from 5130, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 15:
The number 561 fits into 810 1 times, leaving a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 139720.3796791
Subtract 561 from 810 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 16:
If we divide 2490 by 561, we get 4 and a remainder of 246.
Put 4 as the next digit of the answer. 
Result so far: 139720.37967914
If we subtract 2244 from 2490, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Our division results in 139720.37967914 with a remaining 2.46e-07.
