Let's divide 79890669 by 542
We want to figure out the number of times 79890669 can be divided by 542.

Step 1:
When dividing 7 by 542, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 542

Let's proceed to step 2:
79 divided by 542 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 542

On to step 3:
542 goes into 798 1 times with a remainder of 256.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 542 from 798 to get 256.
Append the next digit (9) from the dividend to 256 and continue with: 2569 / 542

On to step 4:
2569 divided by 542 is 4 with a remainder of 401.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2168 from 2569, we get 401.
Take the next digit (0) from the dividend and append it to 401, then repeat: 4010 / 542

Step 5:
542 can be fit into 4010 7 times, resulting in a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 147.0
Deduct 3794 from 4010 and we're left with 216.
Include the next digit (6) from the dividend after 216, then repeat: 2166 / 542

Let's proceed to step 6:
If we divide 2166 by 542, we get 3 and a remainder of 540.
The next digit of our result is 3. 
Result so far: 1473.0
If we subtract 1626 from 2166, we get 540.
Take the next digit (6) from the dividend and append it to 540, then repeat: 5406 / 542

On to step 7:
The number 542 fits into 5406 9 times, leaving a remainder of 528.
Put 9 as the next digit of the answer. 
Result so far: 14739.0
Deduct 4878 from 5406 and we're left with 528.
Fetch the next digit (9) from the dividend, attach it to 528 and continue: 5289 / 542

Let's proceed to step 8:
When dividing 5289 by 542, we get 9 with a remainder of 411.
Put 9 as the next digit of the answer. 
Result so far: 147399.0
If we subtract 4878 from 5289, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 9:
4110 divided by 542 is 7 with a remainder of 316.
Put 7 as the next digit of the answer. 
Result so far: 147399.7
Subtract 3794 from 4110 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
If we divide 3160 by 542, we get 5 and a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 147399.75
Subtract 2710 from 3160 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 11:
4500 divided by 542 is 8 with a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 147399.758
The remainder is 164 after subtracting 4336 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 12:
542 can be fit into 1640 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 147399.7583
Subtracting 1626 from 1640 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
140 divided by 542 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 147399.7583
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
The number 542 fits into 1400 2 times, leaving a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 147399.758302
The remainder is 316 after subtracting 1084 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 15:
542 can be fit into 3160 5 times, resulting in a remainder of 450.
The next digit of our result is 5. 
Result so far: 147399.7583025
If we take 2710 away from 3160, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
The number 542 fits into 4500 8 times, leaving a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 147399.75830258
Subtract 4336 from 4500 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Our division results in 147399.75830258 with a remaining 1.64e-07.
