We look at the division of 78466143 by 49 
We want to divide 78466143 by 49.

Advancing to step 1:
If we divide 7 by 49, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 49

Moving on to step 2:
If we divide 78 by 49, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 78, we end up with 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 49

Let's proceed to step 3:
When dividing 294 by 49, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 294 from 294 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 49

Advancing to step 4:
6 divided by 49 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 49

Let's proceed to step 5:
When dividing 66 by 49, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1601.0
The remainder is 17 after subtracting 49 from 66.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 49

On to step 6:
When dividing 171 by 49, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 16013.0
The remainder is 24 after subtracting 147 from 171.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 49

On to step 7:
The number 49 fits into 244 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 160134.0
Subtracting 196 from 244 leaves us with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 49

On to step 8:
If we divide 483 by 49, we get 9 and a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 1601349.0
If we subtract 441 from 483, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 49, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 1601349.8
Deduct 392 from 420 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
If we divide 280 by 49, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1601349.85
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
The number 49 fits into 350 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1601349.857
Subtract 343 from 350 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 49, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 1601349.8571
Subtract 49 from 70 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1601349.85714
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
When dividing 140 by 49, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 1601349.857142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 15:
If we divide 420 by 49, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1601349.8571428
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 16:
49 can be fit into 280 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1601349.85714285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 1601349.85714285 and a remainder of 3.5e-08.
