55302099 ÷ 781 
We want to figure out the number of times 55302099 can be divided by 781.

Step 1:
781 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 781

Moving on to step 2:
The number 781 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 781

Going ahead to step 3:
553 divided by 781 is 0 with a remainder of 553.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 553 and we're left with 553.
Bring next digit (0) of the dividend behind the 553 and repeat the process: 5530 / 781

Moving on to step 4:
5530 divided by 781 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5467 from 5530 to get 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 781

Step 5:
632 divided by 781 is 0 with a remainder of 632.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 632 after subtracting 0 from 632.
Append the next digit (0) from the dividend to 632 and continue with: 6320 / 781

Moving on to step 6:
If we divide 6320 by 781, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 708.0
Subtract 6248 from 6320 to get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 781

Let's proceed to step 7:
When dividing 729 by 781, we get 0 with a remainder of 729.
Write down 0 as next digit of the result. 
Result so far: 7080.0
The remainder is 729 after subtracting 0 from 729.
Bring next digit (9) of the dividend behind the 729 and repeat the process: 7299 / 781

Going ahead to step 8:
The number 781 fits into 7299 9 times, leaving a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 70809.0
If we take 7029 away from 7299, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 9:
2700 divided by 781 is 3 with a remainder of 357.
The next digit of our result is 3. 
Result so far: 70809.3
Subtracting 2343 from 2700 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 10:
781 can be fit into 3570 4 times, resulting in a remainder of 446.
Put 4 as the next digit of the answer. 
Result so far: 70809.34
If we take 3124 away from 3570, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 11:
When dividing 4460 by 781, we get 5 with a remainder of 555.
Put 5 as the next digit of the answer. 
Result so far: 70809.345
Subtract 3905 from 4460 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 12:
If we divide 5550 by 781, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 70809.3457
Subtracting 5467 from 5550 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 13:
The number 781 fits into 830 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 70809.34571
Deduct 781 from 830 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
781 can be fit into 490 0 times, resulting in a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 70809.34571
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 15:
781 goes into 4900 6 times with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 70809.3457106
Subtracting 4686 from 4900 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 16:
781 goes into 2140 2 times with a remainder of 578.
The number 2 becomes the next digit in our result. 
Result so far: 70809.34571062
If we subtract 1562 from 2140, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Our division results in 70809.34571062 with a remaining 5.78e-07.
