We're dividing 921646 by 51 
Let's see how many times 51 fits into 921646.

Let's proceed to step 1:
51 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 51

On to step 2:
92 divided by 51 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 41 after subtracting 51 from 92.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 51

On to step 3:
If we divide 411 by 51, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 408 from 411, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 51

Advancing to step 4:
51 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 180.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 51

Moving on to step 5:
When dividing 364 by 51, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 1807.0
If we take 357 away from 364, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 51

Going ahead to step 6:
51 goes into 76 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 18071.0
Subtract 51 from 76 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 51, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 18071.4
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
460 divided by 51 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 18071.49
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
If we divide 10 by 51, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 18071.49
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 51 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 18071.4901
Deduct 51 from 100 and we're left 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.

Let's proceed to step 11:
When dividing 490 by 51, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 18071.49019
Subtracting 459 from 490 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
If we divide 310 by 51, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 18071.490196
If we subtract 306 from 310, we 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.

Advancing to step 13:
The number 51 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 18071.490196
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.

Going ahead to step 14:
When dividing 400 by 51, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 18071.49019607
If we take 357 away from 400, we end up 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.

Our division results in 18071.49019607 with a remaining 4.3e-08.
