We're dividing 78637691 by 970 
Let's see how many times 970 fits into 78637691.

Moving on to step 1:
The number 970 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 970

On to step 2:
970 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 970

Moving on to step 3:
786 divided by 970 is 0 with a remainder of 786.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 786 after subtracting 0 from 786.
Append the next digit (3) from the dividend to 786 and continue with: 7863 / 970

Going ahead to step 4:
If we divide 7863 by 970, we get 8 and a remainder of 103.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7760 from 7863 to get 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 970

Let's proceed to step 5:
If we divide 1037 by 970, we get 1 and a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we subtract 970 from 1037, we get 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 970

On to step 6:
970 can be fit into 676 0 times, resulting in a remainder of 676.
Put 0 as the next digit of the answer. 
Result so far: 810.0
Deduct 0 from 676 and we're left with 676.
Grab the next digit (9) from the dividend, add it to 676, then carry on: 6769 / 970

Advancing to step 7:
970 goes into 6769 6 times with a remainder of 949.
The next digit of our result is 6. 
Result so far: 8106.0
If we take 5820 away from 6769, we end up with 949.
Bring next digit (1) of the dividend behind the 949 and repeat the process: 9491 / 970

On to step 8:
970 goes into 9491 9 times with a remainder of 761.
The number 9 becomes the next digit in our result. 
Result so far: 81069.0
The remainder is 761 after subtracting 8730 from 9491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Let's proceed to step 9:
7610 divided by 970 is 7 with a remainder of 820.
Record the quotient 7 as the next digit in the result. 
Result so far: 81069.7
If we subtract 6790 from 7610, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 10:
8200 divided by 970 is 8 with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 81069.78
If we subtract 7760 from 8200, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
When dividing 4400 by 970, we get 4 with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 81069.784
Deduct 3880 from 4400 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
The number 970 fits into 5200 5 times, leaving a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 81069.7845
Subtract 4850 from 5200 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 13:
3500 divided by 970 is 3 with a remainder of 590.
Put 3 as the next digit of the answer. 
Result so far: 81069.78453
Subtracting 2910 from 3500 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 14:
When dividing 5900 by 970, we get 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 81069.784536
Subtract 5820 from 5900 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
If we divide 800 by 970, we get 0 and a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 81069.784536
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 16:
970 can be fit into 8000 8 times, resulting in a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 81069.78453608
If we subtract 7760 from 8000, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 81069.78453608 with a remainder of 2.4e-07.
