70665397 divided by 398 
We're looking to find how many times 398 goes into 70665397.

Let's proceed to step 1:
7 divided by 398 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 398

Let's proceed to step 2:
If we divide 70 by 398, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 398

Going ahead to step 3:
398 can be fit into 706 1 times, resulting in a remainder of 308.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 398 away from 706, we end up with 308.
Append the next digit (6) from the dividend to 308 and continue with: 3086 / 398

Advancing to step 4:
398 goes into 3086 7 times with a remainder of 300.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 2786 from 3086 to get 300.
Include the next digit (5) from the dividend after 300, then repeat: 3005 / 398

Step 5:
If we divide 3005 by 398, we get 7 and a remainder of 219.
Write down 7 as next digit of the result. 
Result so far: 177.0
Deduct 2786 from 3005 and we're left with 219.
Grab the next digit (3) from the dividend, add it to 219, then carry on: 2193 / 398

On to step 6:
The number 398 fits into 2193 5 times, leaving a remainder of 203.
Write down 5 as next digit of the result. 
Result so far: 1775.0
If we subtract 1990 from 2193, we get 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 398

Advancing to step 7:
2039 divided by 398 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 17755.0
If we take 1990 away from 2039, we end up with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 398

On to step 8:
If we divide 497 by 398, we get 1 and a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 177551.0
Subtracting 398 from 497 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
398 goes into 990 2 times with a remainder of 194.
The next digit of our result is 2. 
Result so far: 177551.2
If we take 796 away from 990, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 10:
The number 398 fits into 1940 4 times, leaving a remainder of 348.
The number 4 becomes the next digit in our result. 
Result so far: 177551.24
If we take 1592 away from 1940, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
The number 398 fits into 3480 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 177551.248
Deduct 3184 from 3480 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 12:
If we divide 2960 by 398, we get 7 and a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 177551.2487
If we take 2786 away from 2960, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 13:
The number 398 fits into 1740 4 times, leaving a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 177551.24874
Subtracting 1592 from 1740 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 14:
When dividing 1480 by 398, we get 3 with a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 177551.248743
The remainder is 286 after subtracting 1194 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 15:
398 goes into 2860 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 177551.2487437
The remainder is 74 after subtracting 2786 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 16:
The number 398 fits into 740 1 times, leaving a remainder of 342.
Record the quotient 1 as the next digit in the result. 
Result so far: 177551.24874371
The remainder is 342 after subtracting 398 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final result is 177551.24874371 with a remainder of 3.42e-07.
