98607978 ÷ 429 
Our goal is to divide 98607978 by 429.

Going ahead to step 1:
429 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 429

Moving on to step 2:
The number 429 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 429

Advancing to step 3:
429 goes into 986 2 times with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 858 from 986 and we're left with 128.
Take the next digit (0) from the dividend and append it to 128, then repeat: 1280 / 429

Let's proceed to step 4:
When dividing 1280 by 429, we get 2 with a remainder of 422.
The next digit of our result is 2. 
Result so far: 22.0
If we take 858 away from 1280, we end up with 422.
Take the next digit (7) from the dividend and append it to 422, then repeat: 4227 / 429

Let's proceed to step 5:
The number 429 fits into 4227 9 times, leaving a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
Deduct 3861 from 4227 and we're left with 366.
Append the next digit (9) from the dividend to 366 and continue with: 3669 / 429

Going ahead to step 6:
3669 divided by 429 is 8 with a remainder of 237.
Record the quotient 8 as the next digit in the result. 
Result so far: 2298.0
Subtract 3432 from 3669 to get 237.
Take the next digit (7) from the dividend and append it to 237, then repeat: 2377 / 429

Going ahead to step 7:
2377 divided by 429 is 5 with a remainder of 232.
Write down 5 as next digit of the result. 
Result so far: 22985.0
If we take 2145 away from 2377, we end up with 232.
Grab the next digit (8) from the dividend, add it to 232, then carry on: 2328 / 429

Advancing to step 8:
429 can be fit into 2328 5 times, resulting in a remainder of 183.
Use 5 as the next digit of our solution. 
Result so far: 229855.0
Subtract 2145 from 2328 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
If we divide 1830 by 429, we get 4 and a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 229855.4
If we take 1716 away from 1830, we end up 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.

Advancing to step 10:
If we divide 1140 by 429, we get 2 and a remainder of 282.
The next digit of our result is 2. 
Result so far: 229855.42
If we subtract 858 from 1140, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 11:
2820 divided by 429 is 6 with a remainder of 246.
Record the quotient 6 as the next digit in the result. 
Result so far: 229855.426
The remainder is 246 after subtracting 2574 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 12:
If we divide 2460 by 429, we get 5 and a remainder of 315.
The next digit of our result is 5. 
Result so far: 229855.4265
The remainder is 315 after subtracting 2145 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 13:
429 can be fit into 3150 7 times, resulting in a remainder of 147.
The next digit of our result is 7. 
Result so far: 229855.42657
Subtracting 3003 from 3150 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 14:
429 can be fit into 1470 3 times, resulting in a remainder of 183.
Put 3 as the next digit of the answer. 
Result so far: 229855.426573
If we take 1287 away from 1470, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 15:
When dividing 1830 by 429, we get 4 with a remainder of 114.
The next digit of our result is 4. 
Result so far: 229855.4265734
The remainder is 114 after subtracting 1716 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 16:
1140 divided by 429 is 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 229855.42657342
Subtract 858 from 1140 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

After the division, we end up with 229855.42657342 and a remainder of 2.82e-07.
