838401 divided by 91 
We want to divide 838401 by 91.

On to step 1:
91 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 91

On to step 2:
When dividing 83 by 91, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 91

Step 3:
91 can be fit into 838 9 times, resulting in a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 19 after subtracting 819 from 838.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 91

Moving on to step 4:
91 goes into 194 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 182 from 194 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 91

Step 5:
The number 91 fits into 120 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 921.0
If we subtract 91 from 120, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 91

Moving on to step 6:
If we divide 291 by 91, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 9213.0
Subtracting 273 from 291 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
The number 91 fits into 180 1 times, leaving a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 9213.1
If we take 91 away from 180, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 8:
91 can be fit into 890 9 times, resulting in a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 9213.19
If we subtract 819 from 890, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
91 goes into 710 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 9213.197
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
730 divided by 91 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 9213.1978
Subtracting 728 from 730 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 91 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9213.1978
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 91 fits into 200 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 9213.197802
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
91 goes into 180 1 times with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 9213.1978021
If we take 91 away from 180, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 14:
91 goes into 890 9 times with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 9213.19780219
Subtract 819 from 890 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 9213.19780219 with a remainder of 7.1e-08.
