We look at the division of 29719159 by 431 
We want to divide 29719159 by 431.

Advancing to step 1:
If we divide 2 by 431, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 431

Advancing to step 2:
If we divide 29 by 431, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 431

Advancing to step 3:
The number 431 fits into 297 0 times, leaving a remainder of 297.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 297, we get 297.
Fetch the next digit (1) from the dividend, attach it to 297 and continue: 2971 / 431

Step 4:
431 can be fit into 2971 6 times, resulting in a remainder of 385.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 2586 from 2971, we get 385.
Bring next digit (9) of the dividend behind the 385 and repeat the process: 3859 / 431

Moving on to step 5:
If we divide 3859 by 431, we get 8 and a remainder of 411.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 3448 from 3859 to get 411.
Grab the next digit (1) from the dividend, add it to 411, then carry on: 4111 / 431

Going ahead to step 6:
The number 431 fits into 4111 9 times, leaving a remainder of 232.
The next digit of our result is 9. 
Result so far: 689.0
If we take 3879 away from 4111, we end up with 232.
Bring next digit (5) of the dividend behind the 232 and repeat the process: 2325 / 431

On to step 7:
When dividing 2325 by 431, we get 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 6895.0
Subtracting 2155 from 2325 leaves us with 170.
Append the next digit (9) from the dividend to 170 and continue with: 1709 / 431

Advancing to step 8:
If we divide 1709 by 431, we get 3 and a remainder of 416.
Write down 3 as next digit of the result. 
Result so far: 68953.0
Subtract 1293 from 1709 to get 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:
The number 431 fits into 4160 9 times, leaving a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 68953.9
If we take 3879 away from 4160, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 10:
2810 divided by 431 is 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 68953.96
Deduct 2586 from 2810 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 11:
If we divide 2240 by 431, we get 5 and a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 68953.965
Subtract 2155 from 2240 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 12:
When dividing 850 by 431, we get 1 with a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 68953.9651
The remainder is 419 after subtracting 431 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 13:
431 can be fit into 4190 9 times, resulting in a remainder of 311.
The next digit of our result is 9. 
Result so far: 68953.96519
Subtracting 3879 from 4190 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 14:
The number 431 fits into 3110 7 times, leaving a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 68953.965197
The remainder is 93 after subtracting 3017 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 15:
When dividing 930 by 431, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 68953.9651972
Deduct 862 from 930 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 16:
431 can be fit into 680 1 times, resulting in a remainder of 249.
Put 1 as the next digit of the answer. 
Result so far: 68953.96519721
If we take 431 away from 680, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Our division results in 68953.96519721 with a remaining 2.49e-07.
