We're dividing 70974863 by 987 
We want to divide 70974863 by 987.

Advancing to step 1:
7 divided by 987 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 987

Let's proceed to step 2:
If we divide 70 by 987, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 987

Going ahead to step 3:
When dividing 709 by 987, we get 0 with a remainder of 709.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 709 leaves us with 709.
Grab the next digit (7) from the dividend, add it to 709, then carry on: 7097 / 987

On to step 4:
When dividing 7097 by 987, we get 7 with a remainder of 188.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 6909 from 7097, we get 188.
Include the next digit (4) from the dividend after 188, then repeat: 1884 / 987

Advancing to step 5:
When dividing 1884 by 987, we get 1 with a remainder of 897.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 987 from 1884, we get 897.
Take the next digit (8) from the dividend and append it to 897, then repeat: 8978 / 987

Advancing to step 6:
987 can be fit into 8978 9 times, resulting in a remainder of 95.
Use 9 as the next digit of our solution. 
Result so far: 719.0
Subtract 8883 from 8978 to get 95.
Take the next digit (6) from the dividend and append it to 95, then repeat: 956 / 987

Step 7:
The number 987 fits into 956 0 times, leaving a remainder of 956.
The next digit of our result is 0. 
Result so far: 7190.0
Subtracting 0 from 956 leaves us with 956.
Grab the next digit (3) from the dividend, add it to 956, then carry on: 9563 / 987

Going ahead to step 8:
987 can be fit into 9563 9 times, resulting in a remainder of 680.
The number 9 becomes the next digit in our result. 
Result so far: 71909.0
The remainder is 680 after subtracting 8883 from 9563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 9:
When dividing 6800 by 987, we get 6 with a remainder of 878.
Use 6 as the next digit of our solution. 
Result so far: 71909.6
Subtracting 5922 from 6800 leaves us with 878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8780, and continue the process.

Let's proceed to step 10:
8780 divided by 987 is 8 with a remainder of 884.
Write down 8 as next digit of the result. 
Result so far: 71909.68
If we take 7896 away from 8780, we end up with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

Moving on to step 11:
If we divide 8840 by 987, we get 8 and a remainder of 944.
Write down 8 as next digit of the result. 
Result so far: 71909.688
Deduct 7896 from 8840 and we're left with 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

The final outcome is 71909.688, with a leftover of 0.0944.
