Let's divide 2129975 by 838
Our goal is to divide 2129975 by 838.

Advancing to step 1:
The number 838 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 838

Advancing to step 2:
If we divide 21 by 838, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 838

Advancing to step 3:
The number 838 fits into 212 0 times, leaving a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 838

Moving on to step 4:
838 can be fit into 2129 2 times, resulting in a remainder of 453.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1676 from 2129 and we're left with 453.
Append the next digit (9) from the dividend to 453 and continue with: 4539 / 838

On to step 5:
4539 divided by 838 is 5 with a remainder of 349.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 4190 away from 4539, we end up with 349.
Take the next digit (7) from the dividend and append it to 349, then repeat: 3497 / 838

Let's proceed to step 6:
If we divide 3497 by 838, we get 4 and a remainder of 145.
Use 4 as the next digit of our solution. 
Result so far: 254.0
The remainder is 145 after subtracting 3352 from 3497.
Take the next digit (5) from the dividend and append it to 145, then repeat: 1455 / 838

On to step 7:
838 can be fit into 1455 1 times, resulting in a remainder of 617.
The next digit of our result is 1. 
Result so far: 2541.0
Subtract 838 from 1455 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

On to step 8:
838 goes into 6170 7 times with a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 2541.7
If we take 5866 away from 6170, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 9:
3040 divided by 838 is 3 with a remainder of 526.
Put 3 as the next digit of the answer. 
Result so far: 2541.73
Deduct 2514 from 3040 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 10:
5260 divided by 838 is 6 with a remainder of 232.
The next digit of our result is 6. 
Result so far: 2541.736
If we subtract 5028 from 5260, 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.

On to step 11:
838 can be fit into 2320 2 times, resulting in a remainder of 644.
Use 2 as the next digit of our solution. 
Result so far: 2541.7362
Deduct 1676 from 2320 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Moving on to step 12:
838 can be fit into 6440 7 times, resulting in a remainder of 574.
Put 7 as the next digit of the answer. 
Result so far: 2541.73627
Subtract 5866 from 6440 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 13:
838 goes into 5740 6 times with a remainder of 712.
The number 6 becomes the next digit in our result. 
Result so far: 2541.736276
Subtracting 5028 from 5740 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Advancing to step 14:
838 can be fit into 7120 8 times, resulting in a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 2541.7362768
Deduct 6704 from 7120 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 15:
When dividing 4160 by 838, we get 4 with a remainder of 808.
Use 4 as the next digit of our solution. 
Result so far: 2541.73627684
Subtracting 3352 from 4160 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

The final result is 2541.73627684 with a remainder of 8.08e-07.
