We're dividing 51227642 by 673 
We want to divide 51227642 by 673.

On to step 1:
The number 673 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 673

Let's proceed to step 2:
The number 673 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 673

Let's proceed to step 3:
673 goes into 512 0 times with a remainder of 512.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 512, we get 512.
Include the next digit (2) from the dividend after 512, then repeat: 5122 / 673

Step 4:
The number 673 fits into 5122 7 times, leaving a remainder of 411.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4711 from 5122 leaves us with 411.
Include the next digit (7) from the dividend after 411, then repeat: 4117 / 673

Let's proceed to step 5:
When dividing 4117 by 673, we get 6 with a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 4038 away from 4117, we end up with 79.
Fetch the next digit (6) from the dividend, attach it to 79 and continue: 796 / 673

Moving on to step 6:
When dividing 796 by 673, we get 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 761.0
Subtract 673 from 796 to get 123.
Bring next digit (4) of the dividend behind the 123 and repeat the process: 1234 / 673

On to step 7:
673 goes into 1234 1 times with a remainder of 561.
Use 1 as the next digit of our solution. 
Result so far: 7611.0
The remainder is 561 after subtracting 673 from 1234.
Grab the next digit (2) from the dividend, add it to 561, then carry on: 5612 / 673

Advancing to step 8:
5612 divided by 673 is 8 with a remainder of 228.
The next digit of our result is 8. 
Result so far: 76118.0
Subtract 5384 from 5612 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 9:
If we divide 2280 by 673, we get 3 and a remainder of 261.
Write down 3 as next digit of the result. 
Result so far: 76118.3
Subtracting 2019 from 2280 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 10:
When dividing 2610 by 673, we get 3 with a remainder of 591.
The next digit of our result is 3. 
Result so far: 76118.33
Subtract 2019 from 2610 to get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

The final result is 76118.33 with a remainder of 0.591.
