We look at the division of 35458110 by 838 
We want to figure out the number of times 35458110 can be divided by 838.

Step 1:
838 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 838

Step 2:
When dividing 35 by 838, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 838

Moving on to step 3:
The number 838 fits into 354 0 times, leaving a remainder of 354.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 354 to get 354.
Bring next digit (5) of the dividend behind the 354 and repeat the process: 3545 / 838

On to step 4:
If we divide 3545 by 838, we get 4 and a remainder of 193.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 193 after subtracting 3352 from 3545.
Append the next digit (8) from the dividend to 193 and continue with: 1938 / 838

Step 5:
838 can be fit into 1938 2 times, resulting in a remainder of 262.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1676 from 1938, we get 262.
Append the next digit (1) from the dividend to 262 and continue with: 2621 / 838

Advancing to step 6:
2621 divided by 838 is 3 with a remainder of 107.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
If we take 2514 away from 2621, we end up with 107.
Append the next digit (1) from the dividend to 107 and continue with: 1071 / 838

Step 7:
When dividing 1071 by 838, we get 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 4231.0
If we subtract 838 from 1071, we get 233.
Include the next digit (0) from the dividend after 233, then repeat: 2330 / 838

Going ahead to step 8:
838 goes into 2330 2 times with a remainder of 654.
Put 2 as the next digit of the answer. 
Result so far: 42312.0
Deduct 1676 from 2330 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Let's proceed to step 9:
If we divide 6540 by 838, we get 7 and a remainder of 674.
The number 7 becomes the next digit in our result. 
Result so far: 42312.7
Subtracting 5866 from 6540 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

On to step 10:
If we divide 6740 by 838, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 42312.78
If we subtract 6704 from 6740, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
360 divided by 838 is 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 42312.78
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
3600 divided by 838 is 4 with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 42312.7804
Subtract 3352 from 3600 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
The number 838 fits into 2480 2 times, leaving a remainder of 804.
The next digit of our result is 2. 
Result so far: 42312.78042
The remainder is 804 after subtracting 1676 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Going ahead to step 14:
If we divide 8040 by 838, we get 9 and a remainder of 498.
The next digit of our result is 9. 
Result so far: 42312.780429
If we take 7542 away from 8040, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 15:
4980 divided by 838 is 5 with a remainder of 790.
The number 5 becomes the next digit in our result. 
Result so far: 42312.7804295
If we take 4190 away from 4980, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 16:
When dividing 7900 by 838, we get 9 with a remainder of 358.
Write down 9 as next digit of the result. 
Result so far: 42312.78042959
If we subtract 7542 from 7900, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

After the division, we end up with 42312.78042959 and a remainder of 3.58e-07.
