We divide 971621 by 51
Let's see how many times 51 fits into 971621.

Step 1:
9 divided by 51 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 51

Let's proceed to step 2:
If we divide 97 by 51, we get 1 and a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 51 from 97 leaves us with 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 51

On to step 3:
51 can be fit into 461 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 459 from 461 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 51

Let's proceed to step 4:
If we divide 26 by 51, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 190.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 51

Step 5:
When dividing 262 by 51, we get 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 1905.0
Deduct 255 from 262 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 51

Step 6:
If we divide 71 by 51, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 19051.0
If we subtract 51 from 71, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 51 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 19051.3
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 8:
If we divide 470 by 51, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 19051.39
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 19051.392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 51, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 19051.3921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
If we divide 290 by 51, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 19051.39215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
51 goes into 350 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 19051.392156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
51 goes into 440 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 19051.3921568
Subtracting 408 from 440 leaves us 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.

Moving on to step 14:
320 divided by 51 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 19051.39215686
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.

In conclusion, the division gives 19051.39215686 with a balance of 1.4e-08.
