Let's divide 89779061 by 390
We want to figure out the number of times 89779061 can be divided by 390.

Step 1:
The number 390 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 390

Moving on to step 2:
89 divided by 390 is 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 390

On to step 3:
If we divide 897 by 390, we get 2 and a remainder of 117.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 780 from 897 and we're left with 117.
Fetch the next digit (7) from the dividend, attach it to 117 and continue: 1177 / 390

On to step 4:
390 goes into 1177 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1170 from 1177 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 390

Step 5:
The number 390 fits into 79 0 times, leaving a remainder of 79.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 79 to get 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 390

Step 6:
The number 390 fits into 790 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 2302.0
If we take 780 away from 790, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 390

Moving on to step 7:
If we divide 106 by 390, we get 0 and a remainder of 106.
Record the quotient 0 as the next digit in the result. 
Result so far: 23020.0
If we subtract 0 from 106, we get 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 390

On to step 8:
When dividing 1061 by 390, we get 2 with a remainder of 281.
The number 2 becomes the next digit in our result. 
Result so far: 230202.0
Subtracting 780 from 1061 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 9:
390 can be fit into 2810 7 times, resulting in a remainder of 80.
The next digit of our result is 7. 
Result so far: 230202.7
Subtract 2730 from 2810 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.

Advancing to step 10:
390 goes into 800 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 230202.72
If we subtract 780 from 800, we get 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 11:
390 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 230202.72
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
390 can be fit into 2000 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 230202.7205
Deduct 1950 from 2000 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
When dividing 500 by 390, we get 1 with a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 230202.72051
Subtract 390 from 500 to 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.

Step 14:
If we divide 1100 by 390, we get 2 and a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 230202.720512
Deduct 780 from 1100 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
390 goes into 3200 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 230202.7205128
Subtracting 3120 from 3200 leaves us 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.

Going ahead to step 16:
800 divided by 390 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 230202.72051282
Deduct 780 from 800 and we're left 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.

After the division, we end up with 230202.72051282 and a remainder of 2e-08.
