70137068 ÷ 398 
We're looking to find how many times 398 goes into 70137068.

On to step 1:
When dividing 7 by 398, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 398

Advancing to step 2:
398 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 398

Advancing to step 3:
When dividing 701 by 398, we get 1 with a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 398 from 701 to get 303.
Include the next digit (3) from the dividend after 303, then repeat: 3033 / 398

Advancing to step 4:
398 can be fit into 3033 7 times, resulting in a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2786 from 3033, we get 247.
Include the next digit (7) from the dividend after 247, then repeat: 2477 / 398

Advancing to step 5:
If we divide 2477 by 398, we get 6 and a remainder of 89.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
Deduct 2388 from 2477 and we're left with 89.
Append the next digit (0) from the dividend to 89 and continue with: 890 / 398

Let's proceed to step 6:
398 can be fit into 890 2 times, resulting in a remainder of 94.
The next digit of our result is 2. 
Result so far: 1762.0
If we take 796 away from 890, we end up with 94.
Fetch the next digit (6) from the dividend, attach it to 94 and continue: 946 / 398

On to step 7:
946 divided by 398 is 2 with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 17622.0
If we take 796 away from 946, we end up with 150.
Include the next digit (8) from the dividend after 150, then repeat: 1508 / 398

Going ahead to step 8:
When dividing 1508 by 398, we get 3 with a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 176223.0
The remainder is 314 after subtracting 1194 from 1508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 9:
The number 398 fits into 3140 7 times, leaving a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 176223.7
The remainder is 354 after subtracting 2786 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 10:
When dividing 3540 by 398, we get 8 with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 176223.78
Subtracting 3184 from 3540 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
The number 398 fits into 3560 8 times, leaving a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 176223.788
Subtract 3184 from 3560 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 176223.788 with a remainder of 0.0376.
