Let's divide 68651681 by 435
Our goal is to divide 68651681 by 435.

On to step 1:
435 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 435

Step 2:
435 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 435

Let's proceed to step 3:
435 can be fit into 686 1 times, resulting in a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 435 from 686, we get 251.
Fetch the next digit (5) from the dividend, attach it to 251 and continue: 2515 / 435

Advancing to step 4:
If we divide 2515 by 435, we get 5 and a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2175 from 2515 and we're left with 340.
Take the next digit (1) from the dividend and append it to 340, then repeat: 3401 / 435

Moving on to step 5:
When dividing 3401 by 435, we get 7 with a remainder of 356.
Write down 7 as next digit of the result. 
Result so far: 157.0
Subtracting 3045 from 3401 leaves us with 356.
Include the next digit (6) from the dividend after 356, then repeat: 3566 / 435

Step 6:
3566 divided by 435 is 8 with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 1578.0
Subtract 3480 from 3566 to get 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 435

On to step 7:
If we divide 868 by 435, we get 1 and a remainder of 433.
Write down 1 as next digit of the result. 
Result so far: 15781.0
Subtract 435 from 868 to get 433.
Grab the next digit (1) from the dividend, add it to 433, then carry on: 4331 / 435

Moving on to step 8:
435 goes into 4331 9 times with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 157819.0
If we take 3915 away from 4331, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 9:
435 goes into 4160 9 times with a remainder of 245.
The next digit of our result is 9. 
Result so far: 157819.9
If we take 3915 away from 4160, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
If we divide 2450 by 435, we get 5 and a remainder of 275.
The next digit of our result is 5. 
Result so far: 157819.95
The remainder is 275 after subtracting 2175 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
The number 435 fits into 2750 6 times, leaving a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 157819.956
If we subtract 2610 from 2750, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
When dividing 1400 by 435, we get 3 with a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 157819.9563
Subtracting 1305 from 1400 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
When dividing 950 by 435, we get 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 157819.95632
If we subtract 870 from 950, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
435 goes into 800 1 times with a remainder of 365.
The next digit of our result is 1. 
Result so far: 157819.956321
The remainder is 365 after subtracting 435 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 15:
3650 divided by 435 is 8 with a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 157819.9563218
If we take 3480 away from 3650, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 16:
435 goes into 1700 3 times with a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 157819.95632183
Subtracting 1305 from 1700 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final result is 157819.95632183 with a remainder of 3.95e-07.
