We're dividing 70376970 by 9 
Our goal is to divide 70376970 by 9.

Going ahead to step 1:
When dividing 7 by 9, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 9

Step 2:
The number 9 fits into 70 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 63 from 70 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 9

Moving on to step 3:
73 divided by 9 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 72 from 73 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 9

Moving on to step 4:
9 can be fit into 17 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
If we take 9 away from 17, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 9

Step 5:
The number 9 fits into 86 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 7819.0
Deduct 81 from 86 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 9

Advancing to step 6:
When dividing 59 by 9, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 78196.0
Deduct 54 from 59 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 9

Step 7:
When dividing 57 by 9, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 781966.0
Deduct 54 from 57 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 9

Advancing to step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7819663.0
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 9, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 7819663.3
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
When dividing 30 by 9, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 7819663.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 7819663.33, with a leftover of 0.003.
