79143840 ÷ 170 
Let's see how many times 170 fits into 79143840.

Step 1:
170 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 170

Advancing to step 2:
If we divide 79 by 170, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 170

Let's proceed to step 3:
The number 170 fits into 791 4 times, leaving a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 680 from 791 to get 111.
Append the next digit (4) from the dividend to 111 and continue with: 1114 / 170

Step 4:
When dividing 1114 by 170, we get 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 94 after subtracting 1020 from 1114.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 170

Let's proceed to step 5:
170 goes into 943 5 times with a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 465.0
If we subtract 850 from 943, we get 93.
Append the next digit (8) from the dividend to 93 and continue with: 938 / 170

Let's proceed to step 6:
If we divide 938 by 170, we get 5 and a remainder of 88.
The next digit of our result is 5. 
Result so far: 4655.0
Subtracting 850 from 938 leaves us with 88.
Bring next digit (4) of the dividend behind the 88 and repeat the process: 884 / 170

Advancing to step 7:
The number 170 fits into 884 5 times, leaving a remainder of 34.
The next digit of our result is 5. 
Result so far: 46555.0
The remainder is 34 after subtracting 850 from 884.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 170

Going ahead to step 8:
When dividing 340 by 170, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 465552.0
Deduct 340 from 340 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
170 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 465552.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
When dividing 0 by 170, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 465552.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 465552.0 with a remainder of 0.0.
