We look at the division of 78298061 by 431 
Let's see how many times 431 fits into 78298061.

Going ahead to step 1:
431 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 431

Step 2:
When dividing 78 by 431, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 431

Step 3:
431 can be fit into 782 1 times, resulting in a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 431 from 782, we get 351.
Fetch the next digit (9) from the dividend, attach it to 351 and continue: 3519 / 431

Let's proceed to step 4:
431 can be fit into 3519 8 times, resulting in a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 3448 away from 3519, we end up with 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 431

Going ahead to step 5:
If we divide 718 by 431, we get 1 and a remainder of 287.
The next digit of our result is 1. 
Result so far: 181.0
Subtracting 431 from 718 leaves us with 287.
Grab the next digit (0) from the dividend, add it to 287, then carry on: 2870 / 431

Step 6:
2870 divided by 431 is 6 with a remainder of 284.
The next digit of our result is 6. 
Result so far: 1816.0
Deduct 2586 from 2870 and we're left with 284.
Include the next digit (6) from the dividend after 284, then repeat: 2846 / 431

Step 7:
When dividing 2846 by 431, we get 6 with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 18166.0
Deduct 2586 from 2846 and we're left with 260.
Take the next digit (1) from the dividend and append it to 260, then repeat: 2601 / 431

Moving on to step 8:
The number 431 fits into 2601 6 times, leaving a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 181666.0
If we subtract 2586 from 2601, 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.

Step 9:
The number 431 fits into 150 0 times, leaving a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 181666.0
Subtracting 0 from 150 leaves us 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.

On to step 10:
If we divide 1500 by 431, we get 3 and a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 181666.03
Subtract 1293 from 1500 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 11:
2070 divided by 431 is 4 with a remainder of 346.
Put 4 as the next digit of the answer. 
Result so far: 181666.034
Subtract 1724 from 2070 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 12:
If we divide 3460 by 431, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 181666.0348
The remainder is 12 after subtracting 3448 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 431, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 181666.0348
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
1200 divided by 431 is 2 with a remainder of 338.
The number 2 becomes the next digit in our result. 
Result so far: 181666.034802
The remainder is 338 after subtracting 862 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 15:
431 goes into 3380 7 times with a remainder of 363.
Record the quotient 7 as the next digit in the result. 
Result so far: 181666.0348027
Deduct 3017 from 3380 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 16:
431 can be fit into 3630 8 times, resulting in a remainder of 182.
The next digit of our result is 8. 
Result so far: 181666.03480278
Deduct 3448 from 3630 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 181666.03480278 and a remainder of 1.82e-07.
