Let's divide 51402691 by 985
Our goal is to divide 51402691 by 985.

Going ahead to step 1:
985 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 985

Moving on to step 2:
If we divide 51 by 985, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 985

On to step 3:
514 divided by 985 is 0 with a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 514, we get 514.
Fetch the next digit (0) from the dividend, attach it to 514 and continue: 5140 / 985

Let's proceed to step 4:
985 goes into 5140 5 times with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4925 from 5140 and we're left with 215.
Include the next digit (2) from the dividend after 215, then repeat: 2152 / 985

Step 5:
985 can be fit into 2152 2 times, resulting in a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 1970 from 2152 and we're left with 182.
Fetch the next digit (6) from the dividend, attach it to 182 and continue: 1826 / 985

Advancing to step 6:
If we divide 1826 by 985, we get 1 and a remainder of 841.
The number 1 becomes the next digit in our result. 
Result so far: 521.0
The remainder is 841 after subtracting 985 from 1826.
Include the next digit (9) from the dividend after 841, then repeat: 8419 / 985

On to step 7:
The number 985 fits into 8419 8 times, leaving a remainder of 539.
Use 8 as the next digit of our solution. 
Result so far: 5218.0
Subtract 7880 from 8419 to get 539.
Take the next digit (1) from the dividend and append it to 539, then repeat: 5391 / 985

Moving on to step 8:
If we divide 5391 by 985, we get 5 and a remainder of 466.
Write down 5 as next digit of the result. 
Result so far: 52185.0
The remainder is 466 after subtracting 4925 from 5391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 9:
4660 divided by 985 is 4 with a remainder of 720.
Use 4 as the next digit of our solution. 
Result so far: 52185.4
Deduct 3940 from 4660 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 10:
If we divide 7200 by 985, we get 7 and a remainder of 305.
Write down 7 as next digit of the result. 
Result so far: 52185.47
If we subtract 6895 from 7200, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 11:
985 can be fit into 3050 3 times, resulting in a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 52185.473
The remainder is 95 after subtracting 2955 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 12:
The number 985 fits into 950 0 times, leaving a remainder of 950.
The next digit of our result is 0. 
Result so far: 52185.473
If we subtract 0 from 950, we get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Advancing to step 13:
When dividing 9500 by 985, we get 9 with a remainder of 635.
Write down 9 as next digit of the result. 
Result so far: 52185.47309
Subtracting 8865 from 9500 leaves us with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 14:
985 can be fit into 6350 6 times, resulting in a remainder of 440.
The next digit of our result is 6. 
Result so far: 52185.473096
Subtract 5910 from 6350 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
The number 985 fits into 4400 4 times, leaving a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 52185.4730964
If we take 3940 away from 4400, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 16:
The number 985 fits into 4600 4 times, leaving a remainder of 660.
Record the quotient 4 as the next digit in the result. 
Result so far: 52185.47309644
Subtracting 3940 from 4600 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.

The final outcome is 52185.47309644, with a leftover of 6.6e-07.
