51985379 ÷ 818 
Let's see how many times 818 fits into 51985379.

On to step 1:
If we divide 5 by 818, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 818

Let's proceed to step 2:
If we divide 51 by 818, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 818

Moving on to step 3:
If we divide 519 by 818, we get 0 and a remainder of 519.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 519, we end up with 519.
Grab the next digit (8) from the dividend, add it to 519, then carry on: 5198 / 818

On to step 4:
818 goes into 5198 6 times with a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 4908 from 5198 leaves us with 290.
Bring next digit (5) of the dividend behind the 290 and repeat the process: 2905 / 818

Going ahead to step 5:
2905 divided by 818 is 3 with a remainder of 451.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 451 after subtracting 2454 from 2905.
Append the next digit (3) from the dividend to 451 and continue with: 4513 / 818

Advancing to step 6:
If we divide 4513 by 818, we get 5 and a remainder of 423.
Write down 5 as next digit of the result. 
Result so far: 635.0
The remainder is 423 after subtracting 4090 from 4513.
Append the next digit (7) from the dividend to 423 and continue with: 4237 / 818

Moving on to step 7:
4237 divided by 818 is 5 with a remainder of 147.
The next digit of our result is 5. 
Result so far: 6355.0
If we subtract 4090 from 4237, we get 147.
Bring next digit (9) of the dividend behind the 147 and repeat the process: 1479 / 818

On to step 8:
The number 818 fits into 1479 1 times, leaving a remainder of 661.
Record the quotient 1 as the next digit in the result. 
Result so far: 63551.0
If we subtract 818 from 1479, we get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Let's proceed to step 9:
818 goes into 6610 8 times with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 63551.8
Subtract 6544 from 6610 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
818 goes into 660 0 times with a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 63551.8
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 11:
When dividing 6600 by 818, we get 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 63551.808
If we take 6544 away from 6600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
818 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 63551.808
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
If we divide 5600 by 818, we get 6 and a remainder of 692.
The next digit of our result is 6. 
Result so far: 63551.80806
The remainder is 692 after subtracting 4908 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Advancing to step 14:
If we divide 6920 by 818, we get 8 and a remainder of 376.
Write down 8 as next digit of the result. 
Result so far: 63551.808068
If we subtract 6544 from 6920, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 15:
3760 divided by 818 is 4 with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 63551.8080684
If we take 3272 away from 3760, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 16:
If we divide 4880 by 818, we get 5 and a remainder of 790.
Use 5 as the next digit of our solution. 
Result so far: 63551.80806845
If we take 4090 away from 4880, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

The final outcome is 63551.80806845, with a leftover of 7.9e-07.
