70646854 ÷ 745 
Let's see how many times 745 fits into 70646854.

On to step 1:
745 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 745

Moving on to step 2:
745 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 745

Moving on to step 3:
745 goes into 706 0 times with a remainder of 706.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 706 to get 706.
Bring next digit (4) of the dividend behind the 706 and repeat the process: 7064 / 745

Moving on to step 4:
If we divide 7064 by 745, we get 9 and a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 6705 from 7064 leaves us with 359.
Bring next digit (6) of the dividend behind the 359 and repeat the process: 3596 / 745

Advancing to step 5:
The number 745 fits into 3596 4 times, leaving a remainder of 616.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtract 2980 from 3596 to get 616.
Take the next digit (8) from the dividend and append it to 616, then repeat: 6168 / 745

Let's proceed to step 6:
745 goes into 6168 8 times with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 948.0
The remainder is 208 after subtracting 5960 from 6168.
Grab the next digit (5) from the dividend, add it to 208, then carry on: 2085 / 745

Advancing to step 7:
745 goes into 2085 2 times with a remainder of 595.
The next digit of our result is 2. 
Result so far: 9482.0
If we take 1490 away from 2085, we end up with 595.
Fetch the next digit (4) from the dividend, attach it to 595 and continue: 5954 / 745

Moving on to step 8:
745 goes into 5954 7 times with a remainder of 739.
Use 7 as the next digit of our solution. 
Result so far: 94827.0
If we take 5215 away from 5954, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Moving on to step 9:
745 goes into 7390 9 times with a remainder of 685.
Record the quotient 9 as the next digit in the result. 
Result so far: 94827.9
If we take 6705 away from 7390, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 10:
745 goes into 6850 9 times with a remainder of 145.
The next digit of our result is 9. 
Result so far: 94827.99
Subtracting 6705 from 6850 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 94827.99, with a leftover of 0.145.
