69866780 ÷ 577 
Let's see how many times 577 fits into 69866780.

On to step 1:
577 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 577

On to step 2:
The number 577 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 577

Going ahead to step 3:
The number 577 fits into 698 1 times, leaving a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 577 from 698 leaves us with 121.
Take the next digit (6) from the dividend and append it to 121, then repeat: 1216 / 577

Advancing to step 4:
1216 divided by 577 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1154 away from 1216, we end up with 62.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 577

Going ahead to step 5:
626 divided by 577 is 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 577 from 626 leaves us with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 577

Moving on to step 6:
497 divided by 577 is 0 with a remainder of 497.
Write down 0 as next digit of the result. 
Result so far: 1210.0
If we take 0 away from 497, we end up with 497.
Fetch the next digit (8) from the dividend, attach it to 497 and continue: 4978 / 577

Let's proceed to step 7:
When dividing 4978 by 577, we get 8 with a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 12108.0
Deduct 4616 from 4978 and we're left with 362.
Include the next digit (0) from the dividend after 362, then repeat: 3620 / 577

Going ahead to step 8:
3620 divided by 577 is 6 with a remainder of 158.
Use 6 as the next digit of our solution. 
Result so far: 121086.0
If we subtract 3462 from 3620, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
When dividing 1580 by 577, we get 2 with a remainder of 426.
Put 2 as the next digit of the answer. 
Result so far: 121086.2
The remainder is 426 after subtracting 1154 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 10:
4260 divided by 577 is 7 with a remainder of 221.
Record the quotient 7 as the next digit in the result. 
Result so far: 121086.27
Deduct 4039 from 4260 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 11:
If we divide 2210 by 577, we get 3 and a remainder of 479.
Use 3 as the next digit of our solution. 
Result so far: 121086.273
Subtracting 1731 from 2210 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 12:
The number 577 fits into 4790 8 times, leaving a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 121086.2738
Subtracting 4616 from 4790 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 13:
1740 divided by 577 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 121086.27383
If we subtract 1731 from 1740, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
90 divided by 577 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 121086.27383
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
When dividing 900 by 577, we get 1 with a remainder of 323.
Write down 1 as next digit of the result. 
Result so far: 121086.2738301
Subtract 577 from 900 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 16:
577 can be fit into 3230 5 times, resulting in a remainder of 345.
Write down 5 as next digit of the result. 
Result so far: 121086.27383015
Subtract 2885 from 3230 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

After the division, we end up with 121086.27383015 and a remainder of 3.45e-07.
