78004379 divided by 401 
We want to figure out the number of times 78004379 can be divided by 401.

Going ahead to step 1:
401 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 401

Let's proceed to step 2:
78 divided by 401 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 401

Advancing to step 3:
401 can be fit into 780 1 times, resulting in a remainder of 379.
The next digit of our result is 1. 
Result so far: 1.0
If we take 401 away from 780, we end up with 379.
Include the next digit (0) from the dividend after 379, then repeat: 3790 / 401

Advancing to step 4:
401 goes into 3790 9 times with a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3609 from 3790 to get 181.
Take the next digit (4) from the dividend and append it to 181, then repeat: 1814 / 401

Let's proceed to step 5:
401 goes into 1814 4 times with a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 194.0
Subtracting 1604 from 1814 leaves us with 210.
Grab the next digit (3) from the dividend, add it to 210, then carry on: 2103 / 401

On to step 6:
401 can be fit into 2103 5 times, resulting in a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 1945.0
Subtracting 2005 from 2103 leaves us with 98.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 401

Going ahead to step 7:
The number 401 fits into 987 2 times, leaving a remainder of 185.
The next digit of our result is 2. 
Result so far: 19452.0
The remainder is 185 after subtracting 802 from 987.
Grab the next digit (9) from the dividend, add it to 185, then carry on: 1859 / 401

Advancing to step 8:
401 goes into 1859 4 times with a remainder of 255.
The next digit of our result is 4. 
Result so far: 194524.0
If we subtract 1604 from 1859, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
If we divide 2550 by 401, we get 6 and a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 194524.6
If we subtract 2406 from 2550, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
401 can be fit into 1440 3 times, resulting in a remainder of 237.
Use 3 as the next digit of our solution. 
Result so far: 194524.63
If we take 1203 away from 1440, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Moving on to step 11:
The number 401 fits into 2370 5 times, leaving a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 194524.635
If we subtract 2005 from 2370, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 12:
401 can be fit into 3650 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 194524.6359
If we subtract 3609 from 3650, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
If we divide 410 by 401, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 194524.63591
The remainder is 9 after subtracting 401 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
If we divide 90 by 401, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 194524.63591
Deduct 0 from 90 and we're left 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.

Step 15:
The number 401 fits into 900 2 times, leaving a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 194524.6359102
If we take 802 away from 900, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 16:
401 goes into 980 2 times with a remainder of 178.
The next digit of our result is 2. 
Result so far: 194524.63591022
Subtracting 802 from 980 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final result is 194524.63591022 with a remainder of 1.78e-07.
