617646 divided by 51 
We want to divide 617646 by 51.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 51

Moving on to step 2:
61 divided by 51 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 61, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 51

Moving on to step 3:
107 divided by 51 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 102 from 107 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 51

Let's proceed to step 4:
When dividing 56 by 51, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 121.0
Subtract 51 from 56 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 51

Let's proceed to step 5:
51 can be fit into 54 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
Subtract 51 from 54 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 51

Let's proceed to step 6:
The number 51 fits into 36 0 times, leaving a remainder of 36.
The next digit of our result is 0. 
Result so far: 12110.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12110.7
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
When dividing 30 by 51, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12110.7
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
300 divided by 51 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12110.705
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 12110.7058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 12110.70588
If we take 408 away from 420, 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.

The final outcome is 12110.70588, with a leftover of 1.2e-05.
