We divide 76406 by 51
We want to figure out the number of times 76406 can be divided by 51.

Moving on to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 51

Moving on to step 2:
51 can be fit into 76 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 76, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 51

Advancing to step 3:
If we divide 254 by 51, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 204 from 254, we get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 51

Moving on to step 4:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Deduct 459 from 500 and we're left with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 51

On to step 5:
51 goes into 416 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1498.0
If we subtract 408 from 416, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 6:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1498.1
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1498.15
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 51, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1498.156
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1498.1568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1498.15686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
51 goes into 140 2 times with a remainder of 38.
The next digit of our result is 2. 
Result so far: 1498.156862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 1498.1568627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
51 goes into 230 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1498.15686274
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 1498.15686274 with a remainder of 2.6e-08.
