Let's divide 70423293 by 454
We want to figure out the number of times 70423293 can be divided by 454.

On to step 1:
The number 454 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 454

Going ahead to step 2:
454 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 454

Moving on to step 3:
When dividing 704 by 454, we get 1 with a remainder of 250.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 454 from 704 and we're left with 250.
Bring next digit (2) of the dividend behind the 250 and repeat the process: 2502 / 454

Going ahead to step 4:
454 goes into 2502 5 times with a remainder of 232.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 232 after subtracting 2270 from 2502.
Append the next digit (3) from the dividend to 232 and continue with: 2323 / 454

Moving on to step 5:
454 goes into 2323 5 times with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Deduct 2270 from 2323 and we're left with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 454

Let's proceed to step 6:
The number 454 fits into 532 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 1551.0
Subtract 454 from 532 to get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 454

Going ahead to step 7:
454 can be fit into 789 1 times, resulting in a remainder of 335.
Record the quotient 1 as the next digit in the result. 
Result so far: 15511.0
Deduct 454 from 789 and we're left with 335.
Fetch the next digit (3) from the dividend, attach it to 335 and continue: 3353 / 454

Advancing to step 8:
When dividing 3353 by 454, we get 7 with a remainder of 175.
Write down 7 as next digit of the result. 
Result so far: 155117.0
Subtracting 3178 from 3353 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
If we divide 1750 by 454, we get 3 and a remainder of 388.
Write down 3 as next digit of the result. 
Result so far: 155117.3
If we take 1362 away from 1750, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
If we divide 3880 by 454, we get 8 and a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 155117.38
The remainder is 248 after subtracting 3632 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 11:
If we divide 2480 by 454, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 155117.385
The remainder is 210 after subtracting 2270 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 12:
454 can be fit into 2100 4 times, resulting in a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 155117.3854
If we take 1816 away from 2100, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 13:
The number 454 fits into 2840 6 times, leaving a remainder of 116.
The next digit of our result is 6. 
Result so far: 155117.38546
Subtract 2724 from 2840 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 14:
1160 divided by 454 is 2 with a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 155117.385462
Subtracting 908 from 1160 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 15:
The number 454 fits into 2520 5 times, leaving a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 155117.3854625
If we subtract 2270 from 2520, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 16:
If we divide 2500 by 454, we get 5 and a remainder of 230.
Write down 5 as next digit of the result. 
Result so far: 155117.38546255
Subtracting 2270 from 2500 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 155117.38546255, with a leftover of 2.3e-07.
