We're dividing 61355865 by 51 
We're looking to find how many times 51 goes into 61355865.

Let's proceed to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 51

Moving on to step 2:
The number 51 fits into 61 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 61 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 51

Moving on to step 3:
The number 51 fits into 103 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 102 from 103 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 51

Moving on to step 4:
51 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 15, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 51

On to step 5:
If we divide 155 by 51, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1203.0
Deduct 153 from 155 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 51

Let's proceed to step 6:
When dividing 28 by 51, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 12030.0
Subtract 0 from 28 to get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 51

Going ahead to step 7:
51 can be fit into 286 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 120305.0
If we subtract 255 from 286, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 51

Let's proceed to step 8:
If we divide 315 by 51, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 1203056.0
If we subtract 306 from 315, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1203056.1
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 51 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 1203056.17
If we take 357 away from 390, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
The number 51 fits into 330 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 1203056.176
Deduct 306 from 330 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
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: 1203056.1764
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1203056.17647
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1203056.17647
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.

On to step 15:
When dividing 300 by 51, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1203056.1764705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 16:
When dividing 450 by 51, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 1203056.17647058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 1203056.17647058, with a leftover of 4.2e-08.
