70386580 ÷ 998 
We're looking to find how many times 998 goes into 70386580.

Step 1:
If we divide 7 by 998, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 998

Going ahead to step 2:
The number 998 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 998

Step 3:
998 can be fit into 703 0 times, resulting in a remainder of 703.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 703 after subtracting 0 from 703.
Include the next digit (8) from the dividend after 703, then repeat: 7038 / 998

Let's proceed to step 4:
If we divide 7038 by 998, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6986 from 7038 and we're left with 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 998

Going ahead to step 5:
If we divide 526 by 998, we get 0 and a remainder of 526.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we take 0 away from 526, we end up with 526.
Bring next digit (5) of the dividend behind the 526 and repeat the process: 5265 / 998

Advancing to step 6:
The number 998 fits into 5265 5 times, leaving a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 705.0
If we take 4990 away from 5265, we end up with 275.
Fetch the next digit (8) from the dividend, attach it to 275 and continue: 2758 / 998

Step 7:
998 can be fit into 2758 2 times, resulting in a remainder of 762.
Put 2 as the next digit of the answer. 
Result so far: 7052.0
If we take 1996 away from 2758, we end up with 762.
Append the next digit (0) from the dividend to 762 and continue with: 7620 / 998

Going ahead to step 8:
7620 divided by 998 is 7 with a remainder of 634.
Record the quotient 7 as the next digit in the result. 
Result so far: 70527.0
Subtract 6986 from 7620 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Going ahead to step 9:
998 goes into 6340 6 times with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 70527.6
The remainder is 352 after subtracting 5988 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 10:
The number 998 fits into 3520 3 times, leaving a remainder of 526.
The number 3 becomes the next digit in our result. 
Result so far: 70527.63
If we take 2994 away from 3520, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 11:
5260 divided by 998 is 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 70527.635
Deduct 4990 from 5260 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
998 can be fit into 2700 2 times, resulting in a remainder of 704.
Record the quotient 2 as the next digit in the result. 
Result so far: 70527.6352
Subtract 1996 from 2700 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 13:
If we divide 7040 by 998, we get 7 and a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 70527.63527
If we take 6986 away from 7040, 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.

On to step 14:
998 goes into 540 0 times with a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 70527.63527
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 15:
5400 divided by 998 is 5 with a remainder of 410.
The next digit of our result is 5. 
Result so far: 70527.6352705
If we take 4990 away from 5400, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 16:
When dividing 4100 by 998, we get 4 with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 70527.63527054
Subtract 3992 from 4100 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 70527.63527054 with a remainder of 1.08e-07.
