We divide 84280139 by 838
We want to divide 84280139 by 838.

Advancing to step 1:
8 divided by 838 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 838

On to step 2:
84 divided by 838 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 838

Let's proceed to step 3:
838 can be fit into 842 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 838 from 842 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 838

Going ahead to step 4:
48 divided by 838 is 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 48 after subtracting 0 from 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 838

Advancing to step 5:
The number 838 fits into 480 0 times, leaving a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 480, we get 480.
Grab the next digit (1) from the dividend, add it to 480, then carry on: 4801 / 838

On to step 6:
When dividing 4801 by 838, we get 5 with a remainder of 611.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
The remainder is 611 after subtracting 4190 from 4801.
Append the next digit (3) from the dividend to 611 and continue with: 6113 / 838

Step 7:
838 can be fit into 6113 7 times, resulting in a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 10057.0
Deduct 5866 from 6113 and we're left with 247.
Fetch the next digit (9) from the dividend, attach it to 247 and continue: 2479 / 838

Moving on to step 8:
The number 838 fits into 2479 2 times, leaving a remainder of 803.
Put 2 as the next digit of the answer. 
Result so far: 100572.0
The remainder is 803 after subtracting 1676 from 2479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Let's proceed to step 9:
The number 838 fits into 8030 9 times, leaving a remainder of 488.
Use 9 as the next digit of our solution. 
Result so far: 100572.9
Subtract 7542 from 8030 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 10:
When dividing 4880 by 838, we get 5 with a remainder of 690.
Write down 5 as next digit of the result. 
Result so far: 100572.95
If we subtract 4190 from 4880, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 11:
The number 838 fits into 6900 8 times, leaving a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 100572.958
Deduct 6704 from 6900 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
When dividing 1960 by 838, we get 2 with a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 100572.9582
If we subtract 1676 from 1960, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
838 goes into 2840 3 times with a remainder of 326.
The next digit of our result is 3. 
Result so far: 100572.95823
Subtract 2514 from 2840 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 14:
The number 838 fits into 3260 3 times, leaving a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 100572.958233
If we take 2514 away from 3260, we end up with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

After the division, we end up with 100572.958233 and a remainder of 7.46e-05.
