Let's divide 389958 by 51
We want to figure out the number of times 389958 can be divided by 51.

Going ahead to step 1:
51 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
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.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 51

Advancing to step 3:
When dividing 389 by 51, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 357 from 389, we get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 51

On to step 4:
When dividing 329 by 51, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 306 from 329 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 51

On to step 5:
51 goes into 235 4 times with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 764.0
The remainder is 31 after subtracting 204 from 235.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 51

Moving on to step 6:
51 can be fit into 318 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7646.0
If we take 306 away from 318, 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.

Let's proceed to step 7:
The number 51 fits into 120 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 7646.2
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
51 goes into 180 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 7646.23
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
51 can be fit into 270 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7646.235
Deduct 255 from 270 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
The number 51 fits into 150 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7646.2352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 51 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 7646.23529
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
If we divide 210 by 51, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 7646.235294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 51 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 7646.2352941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 7646.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 7646.23529411 with a remaining 3.9e-08.
