70151807 ÷ 838 
We want to figure out the number of times 70151807 can be divided by 838.

Going ahead to step 1:
When dividing 7 by 838, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 838

On to step 2:
If we divide 70 by 838, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 838

Advancing to step 3:
The number 838 fits into 701 0 times, leaving a remainder of 701.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 701, we get 701.
Append the next digit (5) from the dividend to 701 and continue with: 7015 / 838

Moving on to step 4:
838 can be fit into 7015 8 times, resulting in a remainder of 311.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 311 after subtracting 6704 from 7015.
Append the next digit (1) from the dividend to 311 and continue with: 3111 / 838

On to step 5:
838 can be fit into 3111 3 times, resulting in a remainder of 597.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 2514 from 3111, we get 597.
Append the next digit (8) from the dividend to 597 and continue with: 5978 / 838

Let's proceed to step 6:
5978 divided by 838 is 7 with a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 837.0
Deduct 5866 from 5978 and we're left with 112.
Include the next digit (0) from the dividend after 112, then repeat: 1120 / 838

Moving on to step 7:
When dividing 1120 by 838, we get 1 with a remainder of 282.
Use 1 as the next digit of our solution. 
Result so far: 8371.0
Subtract 838 from 1120 to get 282.
Grab the next digit (7) from the dividend, add it to 282, then carry on: 2827 / 838

Advancing to step 8:
838 can be fit into 2827 3 times, resulting in a remainder of 313.
Use 3 as the next digit of our solution. 
Result so far: 83713.0
Deduct 2514 from 2827 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 9:
The number 838 fits into 3130 3 times, leaving a remainder of 616.
Record the quotient 3 as the next digit in the result. 
Result so far: 83713.3
Deduct 2514 from 3130 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 10:
When dividing 6160 by 838, we get 7 with a remainder of 294.
Write down 7 as next digit of the result. 
Result so far: 83713.37
If we take 5866 away from 6160, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 11:
When dividing 2940 by 838, we get 3 with a remainder of 426.
Record the quotient 3 as the next digit in the result. 
Result so far: 83713.373
If we take 2514 away from 2940, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 12:
The number 838 fits into 4260 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 83713.3735
Subtracting 4190 from 4260 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
If we divide 700 by 838, we get 0 and a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 83713.3735
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 14:
The number 838 fits into 7000 8 times, leaving a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 83713.373508
If we take 6704 away from 7000, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
If we divide 2960 by 838, we get 3 and a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 83713.3735083
Subtracting 2514 from 2960 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 16:
The number 838 fits into 4460 5 times, leaving a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 83713.37350835
If we take 4190 away from 4460, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Our division results in 83713.37350835 with a remaining 2.7e-07.
