73146834 ÷ 70 
Let's see how many times 70 fits into 73146834.

Step 1:
If we divide 7 by 70, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 70

Let's proceed to step 2:
70 goes into 73 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 70 from 73 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 70

Going ahead to step 3:
If we divide 31 by 70, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 70

On to step 4:
When dividing 314 by 70, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 104.0
The remainder is 34 after subtracting 280 from 314.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 70

Moving on to step 5:
70 goes into 346 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 1044.0
The remainder is 66 after subtracting 280 from 346.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 70

On to step 6:
70 goes into 668 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 10449.0
If we take 630 away from 668, we end up with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 70

Let's proceed to step 7:
383 divided by 70 is 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 104495.0
Deduct 350 from 383 and we're left with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 70

On to step 8:
334 divided by 70 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 1044954.0
If we take 280 away from 334, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
540 divided by 70 is 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 1044954.7
Deduct 490 from 540 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1044954.77
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1044954.77 with a remaining 0.01.
