We look at the division of 69971921 by 390 
We want to figure out the number of times 69971921 can be divided by 390.

Going ahead to step 1:
390 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 390

On to step 2:
If we divide 69 by 390, we get 0 and a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 390

Step 3:
390 can be fit into 699 1 times, resulting in a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 390 from 699 leaves us with 309.
Include the next digit (7) from the dividend after 309, then repeat: 3097 / 390

Step 4:
3097 divided by 390 is 7 with a remainder of 367.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 367 after subtracting 2730 from 3097.
Include the next digit (1) from the dividend after 367, then repeat: 3671 / 390

Let's proceed to step 5:
If we divide 3671 by 390, we get 9 and a remainder of 161.
The next digit of our result is 9. 
Result so far: 179.0
If we subtract 3510 from 3671, we get 161.
Include the next digit (9) from the dividend after 161, then repeat: 1619 / 390

Moving on to step 6:
When dividing 1619 by 390, we get 4 with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 1794.0
The remainder is 59 after subtracting 1560 from 1619.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 390

Advancing to step 7:
390 goes into 592 1 times with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 17941.0
Deduct 390 from 592 and we're left with 202.
Bring next digit (1) of the dividend behind the 202 and repeat the process: 2021 / 390

Step 8:
If we divide 2021 by 390, we get 5 and a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 179415.0
If we subtract 1950 from 2021, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
When dividing 710 by 390, we get 1 with a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 179415.1
Subtract 390 from 710 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
3200 divided by 390 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 179415.18
Deduct 3120 from 3200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
If we divide 800 by 390, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 179415.182
Subtracting 780 from 800 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
390 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 179415.182
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
390 goes into 2000 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 179415.18205
Subtract 1950 from 2000 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 390 fits into 500 1 times, leaving a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 179415.182051
If we subtract 390 from 500, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
1100 divided by 390 is 2 with a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 179415.1820512
Subtract 780 from 1100 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 16:
When dividing 3200 by 390, we get 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 179415.18205128
Subtract 3120 from 3200 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.

The quotient of the division is 179415.18205128, and the remainder is 8e-08.
