51986785 ÷ 246 
We want to divide 51986785 by 246.

Step 1:
246 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 246

Going ahead to step 2:
If we divide 51 by 246, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 246

Step 3:
If we divide 519 by 246, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 492 from 519, we get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 246

Advancing to step 4:
The number 246 fits into 278 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 32 after subtracting 246 from 278.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 246

Advancing to step 5:
If we divide 326 by 246, we get 1 and a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Deduct 246 from 326 and we're left with 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 246

Moving on to step 6:
When dividing 807 by 246, we get 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 2113.0
Subtracting 738 from 807 leaves us with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 246

On to step 7:
The number 246 fits into 698 2 times, leaving a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 21132.0
The remainder is 206 after subtracting 492 from 698.
Take the next digit (5) from the dividend and append it to 206, then repeat: 2065 / 246

Let's proceed to step 8:
When dividing 2065 by 246, we get 8 with a remainder of 97.
Use 8 as the next digit of our solution. 
Result so far: 211328.0
The remainder is 97 after subtracting 1968 from 2065.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
When dividing 970 by 246, we get 3 with a remainder of 232.
The next digit of our result is 3. 
Result so far: 211328.3
If we subtract 738 from 970, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
246 goes into 2320 9 times with a remainder of 106.
The next digit of our result is 9. 
Result so far: 211328.39
If we take 2214 away from 2320, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 11:
246 goes into 1060 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 211328.394
If we take 984 away from 1060, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
760 divided by 246 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 211328.3943
If we subtract 738 from 760, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
246 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 211328.3943
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
When dividing 2200 by 246, we get 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 211328.394308
Deduct 1968 from 2200 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 15:
246 goes into 2320 9 times with a remainder of 106.
Write down 9 as next digit of the result. 
Result so far: 211328.3943089
If we take 2214 away from 2320, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 16:
246 can be fit into 1060 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 211328.39430894
If we take 984 away from 1060, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 211328.39430894, with a leftover of 7.6e-08.
