We divide 51921206 by 51
We want to figure out the number of times 51921206 can be divided by 51.

Moving on to step 1:
If we divide 5 by 51, we get 0 and 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 / 51

Going ahead to step 2:
51 goes into 51 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 51 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 51

Going ahead to step 3:
51 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 51

Advancing to step 4:
92 divided by 51 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 51 away from 92, we end up with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 51

Let's proceed to step 5:
When dividing 411 by 51, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 1018.0
If we subtract 408 from 411, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 51

Moving on to step 6:
If we divide 32 by 51, we get 0 and a remainder of 32.
The next digit of our result is 0. 
Result so far: 10180.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 51

Moving on to step 7:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 101806.0
The remainder is 14 after subtracting 306 from 320.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 51

Going ahead to step 8:
If we divide 146 by 51, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1018062.0
If we take 102 away from 146, 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.

Moving on to step 9:
When dividing 440 by 51, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1018062.8
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 1018062.86
If we take 306 away from 320, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 1018062.862
Subtracting 102 from 140 leaves us 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.

Step 12:
51 can be fit into 380 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 1018062.8627
If we subtract 357 from 380, we get 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:
230 divided by 51 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 1018062.86274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
260 divided by 51 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1018062.862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 15:
When dividing 50 by 51, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1018062.862745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
500 divided by 51 is 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 1018062.86274509
Subtract 459 from 500 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 1018062.86274509 with a remainder of 4.1e-08.
