We divide 91921009 by 838
We want to divide 91921009 by 838.

Let's proceed to step 1:
When dividing 9 by 838, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 838

Step 2:
When dividing 91 by 838, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 838

Going ahead to step 3:
838 goes into 919 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 81 after subtracting 838 from 919.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 838

Going ahead to step 4:
The number 838 fits into 812 0 times, leaving a remainder of 812.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 812, we end up with 812.
Append the next digit (1) from the dividend to 812 and continue with: 8121 / 838

Moving on to step 5:
The number 838 fits into 8121 9 times, leaving a remainder of 579.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtracting 7542 from 8121 leaves us with 579.
Fetch the next digit (0) from the dividend, attach it to 579 and continue: 5790 / 838

Moving on to step 6:
838 goes into 5790 6 times with a remainder of 762.
Put 6 as the next digit of the answer. 
Result so far: 1096.0
If we take 5028 away from 5790, we end up with 762.
Fetch the next digit (0) from the dividend, attach it to 762 and continue: 7620 / 838

Advancing to step 7:
838 goes into 7620 9 times with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 10969.0
Subtract 7542 from 7620 to get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 838

Step 8:
If we divide 789 by 838, we get 0 and a remainder of 789.
Record the quotient 0 as the next digit in the result. 
Result so far: 109690.0
If we take 0 away from 789, we end up with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Step 9:
838 goes into 7890 9 times with a remainder of 348.
The next digit of our result is 9. 
Result so far: 109690.9
The remainder is 348 after subtracting 7542 from 7890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
838 goes into 3480 4 times with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 109690.94
Deduct 3352 from 3480 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
1280 divided by 838 is 1 with a remainder of 442.
Write down 1 as next digit of the result. 
Result so far: 109690.941
The remainder is 442 after subtracting 838 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 12:
838 can be fit into 4420 5 times, resulting in a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 109690.9415
Subtracting 4190 from 4420 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
The number 838 fits into 2300 2 times, leaving a remainder of 624.
The next digit of our result is 2. 
Result so far: 109690.94152
If we take 1676 away from 2300, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 14:
If we divide 6240 by 838, we get 7 and a remainder of 374.
Put 7 as the next digit of the answer. 
Result so far: 109690.941527
Deduct 5866 from 6240 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 15:
When dividing 3740 by 838, we get 4 with a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 109690.9415274
If we take 3352 away from 3740, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 16:
838 can be fit into 3880 4 times, resulting in a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 109690.94152744
If we take 3352 away from 3880, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final result is 109690.94152744 with a remainder of 5.28e-07.
