386122 divided by 51 
Let's see how many times 51 fits into 386122.

Moving on to step 1:
3 divided by 51 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 51

On to step 2:
The number 51 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 51

On to step 3:
When dividing 386 by 51, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 357 away from 386, we end up with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 51

On to step 4:
291 divided by 51 is 5 with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Deduct 255 from 291 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 51

Advancing to step 5:
51 goes into 362 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 757.0
The remainder is 5 after subtracting 357 from 362.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 51

Let's proceed to step 6:
If we divide 52 by 51, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 7571.0
Subtract 51 from 52 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 51 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7571.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 7571.01
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
The number 51 fits into 490 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 7571.019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
51 can be fit into 310 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7571.0196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 51, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7571.0196
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 7571.019607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7571.0196078
If we subtract 408 from 430, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
51 goes into 220 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7571.01960784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7571.01960784 and a remainder of 1.6e-08.
