We're dividing 31456791 by 454 
We want to figure out the number of times 31456791 can be divided by 454.

Moving on to step 1:
The number 454 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 454

Let's proceed to step 2:
If we divide 31 by 454, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 454

Advancing to step 3:
454 goes into 314 0 times with a remainder of 314.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 314 leaves us with 314.
Take the next digit (5) from the dividend and append it to 314, then repeat: 3145 / 454

On to step 4:
454 can be fit into 3145 6 times, resulting in a remainder of 421.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 2724 from 3145 and we're left with 421.
Fetch the next digit (6) from the dividend, attach it to 421 and continue: 4216 / 454

Advancing to step 5:
454 can be fit into 4216 9 times, resulting in a remainder of 130.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtract 4086 from 4216 to get 130.
Fetch the next digit (7) from the dividend, attach it to 130 and continue: 1307 / 454

On to step 6:
454 can be fit into 1307 2 times, resulting in a remainder of 399.
The next digit of our result is 2. 
Result so far: 692.0
The remainder is 399 after subtracting 908 from 1307.
Append the next digit (9) from the dividend to 399 and continue with: 3999 / 454

Going ahead to step 7:
The number 454 fits into 3999 8 times, leaving a remainder of 367.
The next digit of our result is 8. 
Result so far: 6928.0
If we take 3632 away from 3999, we end up with 367.
Include the next digit (1) from the dividend after 367, then repeat: 3671 / 454

On to step 8:
If we divide 3671 by 454, we get 8 and a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 69288.0
The remainder is 39 after subtracting 3632 from 3671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 454, we get 0 and a remainder of 390.
The next digit of our result is 0. 
Result so far: 69288.0
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
454 goes into 3900 8 times with a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 69288.08
Subtracting 3632 from 3900 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
454 goes into 2680 5 times with a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 69288.085
Subtracting 2270 from 2680 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 12:
If we divide 4100 by 454, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 69288.0859
The remainder is 14 after subtracting 4086 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
454 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 69288.0859
If we subtract 0 from 140, 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.

Let's proceed to step 14:
454 can be fit into 1400 3 times, resulting in a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 69288.085903
Deduct 1362 from 1400 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 15:
The number 454 fits into 380 0 times, leaving a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 69288.085903
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
454 goes into 3800 8 times with a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 69288.08590308
The remainder is 168 after subtracting 3632 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 69288.08590308 with a remainder of 1.68e-07.
