We look at the division of 79961435 by 998 
We want to figure out the number of times 79961435 can be divided by 998.

On to step 1:
If we divide 7 by 998, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 998

Advancing to step 2:
998 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 998

Going ahead to step 3:
998 goes into 799 0 times with a remainder of 799.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 799 and we're left with 799.
Append the next digit (6) from the dividend to 799 and continue with: 7996 / 998

On to step 4:
7996 divided by 998 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7984 from 7996 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 998

Advancing to step 5:
121 divided by 998 is 0 with a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 121, we end up with 121.
Take the next digit (4) from the dividend and append it to 121, then repeat: 1214 / 998

Moving on to step 6:
If we divide 1214 by 998, we get 1 and a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 801.0
Subtract 998 from 1214 to get 216.
Include the next digit (3) from the dividend after 216, then repeat: 2163 / 998

Advancing to step 7:
If we divide 2163 by 998, we get 2 and a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 8012.0
If we take 1996 away from 2163, we end up with 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 998

Step 8:
998 can be fit into 1675 1 times, resulting in a remainder of 677.
Write down 1 as next digit of the result. 
Result so far: 80121.0
Deduct 998 from 1675 and we're left with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Step 9:
The number 998 fits into 6770 6 times, leaving a remainder of 782.
The next digit of our result is 6. 
Result so far: 80121.6
Subtract 5988 from 6770 to get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Let's proceed to step 10:
998 goes into 7820 7 times with a remainder of 834.
Use 7 as the next digit of our solution. 
Result so far: 80121.67
If we take 6986 away from 7820, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 11:
When dividing 8340 by 998, we get 8 with a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 80121.678
If we take 7984 away from 8340, we end up 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.

Step 12:
The number 998 fits into 3560 3 times, leaving a remainder of 566.
Use 3 as the next digit of our solution. 
Result so far: 80121.6783
If we subtract 2994 from 3560, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 13:
5660 divided by 998 is 5 with a remainder of 670.
Put 5 as the next digit of the answer. 
Result so far: 80121.67835
If we take 4990 away from 5660, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 14:
998 goes into 6700 6 times with a remainder of 712.
Write down 6 as next digit of the result. 
Result so far: 80121.678356
The remainder is 712 after subtracting 5988 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 15:
When dividing 7120 by 998, we get 7 with a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 80121.6783567
If we subtract 6986 from 7120, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 16:
998 goes into 1340 1 times with a remainder of 342.
Record the quotient 1 as the next digit in the result. 
Result so far: 80121.67835671
If we take 998 away from 1340, we end up with 342.
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 outcome is 80121.67835671, with a leftover of 3.42e-07.
