We're dividing 51218133 by 986 
We're looking to find how many times 986 goes into 51218133.

Moving on to step 1:
The number 986 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 986

Going ahead to step 2:
The number 986 fits into 51 0 times, leaving 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.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 986

On to step 3:
When dividing 512 by 986, we get 0 with a remainder of 512.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 512 to get 512.
Fetch the next digit (1) from the dividend, attach it to 512 and continue: 5121 / 986

Going ahead to step 4:
The number 986 fits into 5121 5 times, leaving a remainder of 191.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4930 from 5121, we get 191.
Take the next digit (8) from the dividend and append it to 191, then repeat: 1918 / 986

Advancing to step 5:
986 can be fit into 1918 1 times, resulting in a remainder of 932.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 986 from 1918, we get 932.
Append the next digit (1) from the dividend to 932 and continue with: 9321 / 986

Moving on to step 6:
When dividing 9321 by 986, we get 9 with a remainder of 447.
The next digit of our result is 9. 
Result so far: 519.0
Subtracting 8874 from 9321 leaves us with 447.
Take the next digit (3) from the dividend and append it to 447, then repeat: 4473 / 986

Going ahead to step 7:
If we divide 4473 by 986, we get 4 and a remainder of 529.
The next digit of our result is 4. 
Result so far: 5194.0
Subtracting 3944 from 4473 leaves us with 529.
Include the next digit (3) from the dividend after 529, then repeat: 5293 / 986

Moving on to step 8:
986 can be fit into 5293 5 times, resulting in a remainder of 363.
Write down 5 as next digit of the result. 
Result so far: 51945.0
If we subtract 4930 from 5293, we get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 9:
The number 986 fits into 3630 3 times, leaving a remainder of 672.
Use 3 as the next digit of our solution. 
Result so far: 51945.3
The remainder is 672 after subtracting 2958 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 10:
If we divide 6720 by 986, we get 6 and a remainder of 804.
Put 6 as the next digit of the answer. 
Result so far: 51945.36
If we subtract 5916 from 6720, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 11:
8040 divided by 986 is 8 with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 51945.368
If we subtract 7888 from 8040, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
The number 986 fits into 1520 1 times, leaving a remainder of 534.
Use 1 as the next digit of our solution. 
Result so far: 51945.3681
The remainder is 534 after subtracting 986 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 13:
986 goes into 5340 5 times with a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 51945.36815
Subtract 4930 from 5340 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
When dividing 4100 by 986, we get 4 with a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 51945.368154
Subtracting 3944 from 4100 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 15:
1560 divided by 986 is 1 with a remainder of 574.
The next digit of our result is 1. 
Result so far: 51945.3681541
If we take 986 away from 1560, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 16:
986 can be fit into 5740 5 times, resulting in a remainder of 810.
Record the quotient 5 as the next digit in the result. 
Result so far: 51945.36815415
If we subtract 4930 from 5740, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

After the division, we end up with 51945.36815415 and a remainder of 8.1e-07.
