386757 divided by 51 
We want to divide 386757 by 51.

Moving on to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 51

Let's proceed to step 2:
When dividing 38 by 51, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 51

Let's proceed to step 3:
51 can be fit into 386 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 29 after subtracting 357 from 386.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 51

Going ahead to step 4:
51 can be fit into 297 5 times, resulting in a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtract 255 from 297 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 51

Advancing to step 5:
When dividing 425 by 51, we get 8 with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 758.0
Subtract 408 from 425 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 51

Moving on to step 6:
The number 51 fits into 177 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 7583.0
If we subtract 153 from 177, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7583.4
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
If we divide 360 by 51, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7583.47
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
If we divide 30 by 51, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7583.47
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 7583.4705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
450 divided by 51 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 7583.47058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 7583.470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 7583.470588 with a remaining 1.2e-06.
