Let's divide 900139 by 71
Let's see how many times 71 fits into 900139.

Step 1:
When dividing 9 by 71, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 71

Step 2:
When dividing 90 by 71, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 71 away from 90, we end up with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 71

Let's proceed to step 3:
When dividing 190 by 71, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 142 away from 190, we end up with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 71

Moving on to step 4:
The number 71 fits into 481 6 times, leaving a remainder of 55.
The next digit of our result is 6. 
Result so far: 126.0
Deduct 426 from 481 and we're left with 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 71

Let's proceed to step 5:
If we divide 553 by 71, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 1267.0
Deduct 497 from 553 and we're left with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 71

Advancing to step 6:
The number 71 fits into 569 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 12678.0
If we subtract 568 from 569, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 71, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12678.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
71 can be fit into 100 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 12678.01
Deduct 71 from 100 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
When dividing 290 by 71, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 12678.014
The remainder is 6 after subtracting 284 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
71 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12678.014
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 71 fits into 600 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 12678.01408
Deduct 568 from 600 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
320 divided by 71 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 12678.014084
Subtract 284 from 320 to 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.

Step 13:
The number 71 fits into 360 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12678.0140845
If we take 355 away from 360, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
71 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12678.0140845
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 12678.0140845 with a remainder of 5e-08.
