We're dividing 78100801 by 351 
We want to figure out the number of times 78100801 can be divided by 351.

Let's proceed to step 1:
When dividing 7 by 351, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 351

Let's proceed to step 2:
351 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 351

Going ahead to step 3:
351 goes into 781 2 times with a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 79 after subtracting 702 from 781.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 351

Moving on to step 4:
The number 351 fits into 790 2 times, leaving a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 88 after subtracting 702 from 790.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 351

On to step 5:
When dividing 880 by 351, we get 2 with a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 222.0
If we take 702 away from 880, we end up with 178.
Take the next digit (8) from the dividend and append it to 178, then repeat: 1788 / 351

Advancing to step 6:
1788 divided by 351 is 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 2225.0
If we subtract 1755 from 1788, we get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 351

Going ahead to step 7:
351 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 22250.0
Subtract 0 from 330 to get 330.
Grab the next digit (1) from the dividend, add it to 330, then carry on: 3301 / 351

Going ahead to step 8:
351 can be fit into 3301 9 times, resulting in a remainder of 142.
The next digit of our result is 9. 
Result so far: 222509.0
Subtract 3159 from 3301 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
The number 351 fits into 1420 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 222509.4
If we take 1404 away from 1420, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
351 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 222509.4
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
1600 divided by 351 is 4 with a remainder of 196.
The next digit of our result is 4. 
Result so far: 222509.404
If we take 1404 away from 1600, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 12:
351 can be fit into 1960 5 times, resulting in a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 222509.4045
If we take 1755 away from 1960, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 13:
The number 351 fits into 2050 5 times, leaving a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 222509.40455
If we subtract 1755 from 2050, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Our division results in 222509.40455 with a remaining 0.000295.
