Let's divide 78933882 by 401
We want to figure out the number of times 78933882 can be divided by 401.

Going ahead to step 1:
If we divide 7 by 401, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 401

Step 2:
The number 401 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 401

Step 3:
789 divided by 401 is 1 with a remainder of 388.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 401 from 789 to get 388.
Take the next digit (3) from the dividend and append it to 388, then repeat: 3883 / 401

Let's proceed to step 4:
When dividing 3883 by 401, we get 9 with a remainder of 274.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 274 after subtracting 3609 from 3883.
Append the next digit (3) from the dividend to 274 and continue with: 2743 / 401

Going ahead to step 5:
When dividing 2743 by 401, we get 6 with a remainder of 337.
Use 6 as the next digit of our solution. 
Result so far: 196.0
The remainder is 337 after subtracting 2406 from 2743.
Fetch the next digit (8) from the dividend, attach it to 337 and continue: 3378 / 401

Moving on to step 6:
401 can be fit into 3378 8 times, resulting in a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 1968.0
Deduct 3208 from 3378 and we're left with 170.
Bring next digit (8) of the dividend behind the 170 and repeat the process: 1708 / 401

Going ahead to step 7:
401 goes into 1708 4 times with a remainder of 104.
The next digit of our result is 4. 
Result so far: 19684.0
If we subtract 1604 from 1708, we get 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 401

Advancing to step 8:
The number 401 fits into 1042 2 times, leaving a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 196842.0
Subtract 802 from 1042 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 9:
2400 divided by 401 is 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 196842.5
Subtract 2005 from 2400 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
When dividing 3950 by 401, we get 9 with a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 196842.59
Deduct 3609 from 3950 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 11:
The number 401 fits into 3410 8 times, leaving a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 196842.598
Deduct 3208 from 3410 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 12:
401 goes into 2020 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 196842.5985
Subtracting 2005 from 2020 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 401 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 196842.5985
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
1500 divided by 401 is 3 with a remainder of 297.
The next digit of our result is 3. 
Result so far: 196842.598503
Subtracting 1203 from 1500 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 15:
The number 401 fits into 2970 7 times, leaving a remainder of 163.
Write down 7 as next digit of the result. 
Result so far: 196842.5985037
If we take 2807 away from 2970, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 16:
401 can be fit into 1630 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 196842.59850374
If we subtract 1604 from 1630, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 196842.59850374 with a remainder of 2.6e-08.
