Let's divide 78083139 by 426
Our goal is to divide 78083139 by 426.

Advancing to step 1:
The number 426 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 426

Going ahead to step 2:
The number 426 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 426

Moving on to step 3:
426 goes into 780 1 times with a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 426 from 780, we get 354.
Fetch the next digit (8) from the dividend, attach it to 354 and continue: 3548 / 426

Advancing to step 4:
3548 divided by 426 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 140 after subtracting 3408 from 3548.
Fetch the next digit (3) from the dividend, attach it to 140 and continue: 1403 / 426

Let's proceed to step 5:
426 goes into 1403 3 times with a remainder of 125.
The next digit of our result is 3. 
Result so far: 183.0
Deduct 1278 from 1403 and we're left with 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 426

Moving on to step 6:
When dividing 1251 by 426, we get 2 with a remainder of 399.
Record the quotient 2 as the next digit in the result. 
Result so far: 1832.0
Subtract 852 from 1251 to get 399.
Include the next digit (3) from the dividend after 399, then repeat: 3993 / 426

Moving on to step 7:
426 can be fit into 3993 9 times, resulting in a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 18329.0
If we subtract 3834 from 3993, we get 159.
Include the next digit (9) from the dividend after 159, then repeat: 1599 / 426

Moving on to step 8:
The number 426 fits into 1599 3 times, leaving a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 183293.0
If we subtract 1278 from 1599, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 9:
426 can be fit into 3210 7 times, resulting in a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 183293.7
Deduct 2982 from 3210 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 10:
426 can be fit into 2280 5 times, resulting in a remainder of 150.
The next digit of our result is 5. 
Result so far: 183293.75
Deduct 2130 from 2280 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.

Going ahead to step 11:
426 can be fit into 1500 3 times, resulting in a remainder of 222.
The number 3 becomes the next digit in our result. 
Result so far: 183293.753
The remainder is 222 after subtracting 1278 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 12:
If we divide 2220 by 426, we get 5 and a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 183293.7535
If we subtract 2130 from 2220, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
426 goes into 900 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 183293.75352
If we take 852 away from 900, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
426 goes into 480 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 183293.753521
The remainder is 54 after subtracting 426 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
The number 426 fits into 540 1 times, leaving a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 183293.7535211
Deduct 426 from 540 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final outcome is 183293.7535211, with a leftover of 1.14e-06.
