We're dividing 51998581 by 412 
We want to figure out the number of times 51998581 can be divided by 412.

Let's proceed to step 1:
5 divided by 412 is 0 with a remainder of 5.
The next digit of our result is 0. 
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 / 412

Going ahead to step 2:
412 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 412

Moving on to step 3:
412 can be fit into 519 1 times, resulting in a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 412 from 519 to get 107.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 412

On to step 4:
412 can be fit into 1079 2 times, resulting in a remainder of 255.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 255 after subtracting 824 from 1079.
Grab the next digit (8) from the dividend, add it to 255, then carry on: 2558 / 412

Going ahead to step 5:
If we divide 2558 by 412, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 2472 away from 2558, we end up with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 412

Let's proceed to step 6:
412 can be fit into 865 2 times, resulting in a remainder of 41.
Put 2 as the next digit of the answer. 
Result so far: 1262.0
Subtract 824 from 865 to get 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 412

Step 7:
When dividing 418 by 412, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 12621.0
Subtracting 412 from 418 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 412

Let's proceed to step 8:
412 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 126210.0
Subtracting 0 from 61 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
412 can be fit into 610 1 times, resulting in a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 126210.1
If we take 412 away from 610, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
1980 divided by 412 is 4 with a remainder of 332.
Write down 4 as next digit of the result. 
Result so far: 126210.14
If we subtract 1648 from 1980, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 11:
The number 412 fits into 3320 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 126210.148
Subtract 3296 from 3320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 412, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 126210.148
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
If we divide 2400 by 412, we get 5 and a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 126210.14805
The remainder is 340 after subtracting 2060 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
3400 divided by 412 is 8 with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 126210.148058
Subtract 3296 from 3400 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
412 goes into 1040 2 times with a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 126210.1480582
If we take 824 away from 1040, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 16:
412 goes into 2160 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 126210.14805825
If we take 2060 away from 2160, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 126210.14805825, with a leftover of 1e-07.
