611820 ÷ 51 
We want to figure out the number of times 611820 can be divided by 51.

Going ahead to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 51

Advancing to step 2:
61 divided by 51 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 51 from 61 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 51

Moving on to step 3:
If we divide 101 by 51, we get 1 and a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 51 away from 101, we end up with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 51

Moving on to step 4:
51 goes into 508 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtracting 459 from 508 leaves us with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 51

Let's proceed to step 5:
492 divided by 51 is 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 1199.0
Deduct 459 from 492 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 51

Advancing to step 6:
330 divided by 51 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 11996.0
If we subtract 306 from 330, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
The number 51 fits into 240 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 11996.4
Deduct 204 from 240 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
51 goes into 360 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 11996.47
Subtracting 357 from 360 leaves us with 3.
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 9:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 11996.47
The remainder is 30 after subtracting 0 from 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 10:
If we divide 300 by 51, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 11996.4705
Deduct 255 from 300 and we're left 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.

Let's proceed to step 11:
When dividing 450 by 51, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 11996.47058
If we take 408 away from 450, we end up 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 12:
When dividing 420 by 51, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 11996.470588
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 11996.470588, with a leftover of 1.2e-06.
