7138145 ÷ 904 
We want to divide 7138145 by 904.

Going ahead to step 1:
904 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 904

Step 2:
The number 904 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 904

On to step 3:
713 divided by 904 is 0 with a remainder of 713.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 713 after subtracting 0 from 713.
Fetch the next digit (8) from the dividend, attach it to 713 and continue: 7138 / 904

Moving on to step 4:
When dividing 7138 by 904, we get 7 with a remainder of 810.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6328 away from 7138, we end up with 810.
Grab the next digit (1) from the dividend, add it to 810, then carry on: 8101 / 904

Let's proceed to step 5:
If we divide 8101 by 904, we get 8 and a remainder of 869.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 7232 away from 8101, we end up with 869.
Append the next digit (4) from the dividend to 869 and continue with: 8694 / 904

On to step 6:
8694 divided by 904 is 9 with a remainder of 558.
The next digit of our result is 9. 
Result so far: 789.0
Subtracting 8136 from 8694 leaves us with 558.
Bring next digit (5) of the dividend behind the 558 and repeat the process: 5585 / 904

On to step 7:
The number 904 fits into 5585 6 times, leaving a remainder of 161.
Record the quotient 6 as the next digit in the result. 
Result so far: 7896.0
If we take 5424 away from 5585, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 8:
1610 divided by 904 is 1 with a remainder of 706.
Write down 1 as next digit of the result. 
Result so far: 7896.1
The remainder is 706 after subtracting 904 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Step 9:
7060 divided by 904 is 7 with a remainder of 732.
Put 7 as the next digit of the answer. 
Result so far: 7896.17
Subtract 6328 from 7060 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 10:
When dividing 7320 by 904, we get 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 7896.178
The remainder is 88 after subtracting 7232 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
When dividing 880 by 904, we get 0 with a remainder of 880.
Use 0 as the next digit of our solution. 
Result so far: 7896.178
If we take 0 away from 880, we end up with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Advancing to step 12:
If we divide 8800 by 904, we get 9 and a remainder of 664.
Record the quotient 9 as the next digit in the result. 
Result so far: 7896.17809
Deduct 8136 from 8800 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 13:
6640 divided by 904 is 7 with a remainder of 312.
The next digit of our result is 7. 
Result so far: 7896.178097
Deduct 6328 from 6640 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 14:
When dividing 3120 by 904, we get 3 with a remainder of 408.
Write down 3 as next digit of the result. 
Result so far: 7896.1780973
Deduct 2712 from 3120 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 15:
If we divide 4080 by 904, we get 4 and a remainder of 464.
The next digit of our result is 4. 
Result so far: 7896.17809734
Deduct 3616 from 4080 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Our division results in 7896.17809734 with a remaining 4.64e-07.
