We're dividing 69971086 by 990 
We want to divide 69971086 by 990.

On to step 1:
The number 990 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 990

On to step 2:
990 goes into 69 0 times with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 990

Step 3:
If we divide 699 by 990, we get 0 and a remainder of 699.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 699, we end up with 699.
Append the next digit (7) from the dividend to 699 and continue with: 6997 / 990

Step 4:
990 can be fit into 6997 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6930 from 6997 and we're left with 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 990

Moving on to step 5:
671 divided by 990 is 0 with a remainder of 671.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 671, we end up with 671.
Append the next digit (0) from the dividend to 671 and continue with: 6710 / 990

Let's proceed to step 6:
If we divide 6710 by 990, we get 6 and a remainder of 770.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
If we subtract 5940 from 6710, we get 770.
Include the next digit (8) from the dividend after 770, then repeat: 7708 / 990

Going ahead to step 7:
990 can be fit into 7708 7 times, resulting in a remainder of 778.
Put 7 as the next digit of the answer. 
Result so far: 7067.0
The remainder is 778 after subtracting 6930 from 7708.
Bring next digit (6) of the dividend behind the 778 and repeat the process: 7786 / 990

Advancing to step 8:
When dividing 7786 by 990, we get 7 with a remainder of 856.
Record the quotient 7 as the next digit in the result. 
Result so far: 70677.0
Deduct 6930 from 7786 and we're left with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 9:
990 can be fit into 8560 8 times, resulting in a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 70677.8
Deduct 7920 from 8560 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 10:
990 goes into 6400 6 times with a remainder of 460.
The number 6 becomes the next digit in our result. 
Result so far: 70677.86
If we take 5940 away from 6400, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
990 goes into 4600 4 times with a remainder of 640.
The number 4 becomes the next digit in our result. 
Result so far: 70677.864
If we subtract 3960 from 4600, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 12:
990 can be fit into 6400 6 times, resulting in a remainder of 460.
Record the quotient 6 as the next digit in the result. 
Result so far: 70677.8646
If we take 5940 away from 6400, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
990 can be fit into 4600 4 times, resulting in a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 70677.86464
Deduct 3960 from 4600 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
6400 divided by 990 is 6 with a remainder of 460.
Write down 6 as next digit of the result. 
Result so far: 70677.864646
If we subtract 5940 from 6400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 15:
990 can be fit into 4600 4 times, resulting in a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 70677.8646464
If we take 3960 away from 4600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 16:
6400 divided by 990 is 6 with a remainder of 460.
The next digit of our result is 6. 
Result so far: 70677.86464646
If we subtract 5940 from 6400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 70677.86464646, with a leftover of 4.6e-07.
