78139371 divided by 195 
We want to divide 78139371 by 195.

Advancing to step 1:
The number 195 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 195

Let's proceed to step 2:
When dividing 78 by 195, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 195

Moving on to step 3:
If we divide 781 by 195, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 780 from 781, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 195

On to step 4:
If we divide 13 by 195, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 195

Let's proceed to step 5:
195 goes into 139 0 times with a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
The remainder is 139 after subtracting 0 from 139.
Take the next digit (3) from the dividend and append it to 139, then repeat: 1393 / 195

Going ahead to step 6:
195 goes into 1393 7 times with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 4007.0
If we take 1365 away from 1393, we end up with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 195

On to step 7:
195 can be fit into 287 1 times, resulting in a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 40071.0
If we take 195 away from 287, we end up with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 195

Going ahead to step 8:
If we divide 921 by 195, we get 4 and a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 400714.0
Subtract 780 from 921 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
195 goes into 1410 7 times with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 400714.7
Deduct 1365 from 1410 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
195 can be fit into 450 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 400714.72
Deduct 390 from 450 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
195 goes into 600 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 400714.723
If we subtract 585 from 600, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
195 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 400714.723
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 13:
When dividing 1500 by 195, we get 7 with a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 400714.72307
Deduct 1365 from 1500 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 14:
If we divide 1350 by 195, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 400714.723076
If we take 1170 away from 1350, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 15:
The number 195 fits into 1800 9 times, leaving a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 400714.7230769
Subtract 1755 from 1800 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 16:
The number 195 fits into 450 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 400714.72307692
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 400714.72307692, with a leftover of 6e-08.
