Let's divide 42117107 by 181
We want to figure out the number of times 42117107 can be divided by 181.

Step 1:
181 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 181

Step 2:
If we divide 42 by 181, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 181

Step 3:
If we divide 421 by 181, we get 2 and a remainder of 59.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 362 from 421, we get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 181

Let's proceed to step 4:
The number 181 fits into 591 3 times, leaving a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 48 after subtracting 543 from 591.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 181

Advancing to step 5:
The number 181 fits into 487 2 times, leaving a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Subtract 362 from 487 to get 125.
Take the next digit (1) from the dividend and append it to 125, then repeat: 1251 / 181

Going ahead to step 6:
181 can be fit into 1251 6 times, resulting in a remainder of 165.
The number 6 becomes the next digit in our result. 
Result so far: 2326.0
If we subtract 1086 from 1251, we get 165.
Grab the next digit (0) from the dividend, add it to 165, then carry on: 1650 / 181

Advancing to step 7:
If we divide 1650 by 181, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 23269.0
If we take 1629 away from 1650, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 181

Going ahead to step 8:
217 divided by 181 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 232691.0
Subtracting 181 from 217 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 181 fits into 360 1 times, leaving a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 232691.1
Subtract 181 from 360 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 10:
181 goes into 1790 9 times with a remainder of 161.
The next digit of our result is 9. 
Result so far: 232691.19
Subtracting 1629 from 1790 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 11:
181 can be fit into 1610 8 times, resulting in a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 232691.198
Deduct 1448 from 1610 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 12:
1620 divided by 181 is 8 with a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 232691.1988
The remainder is 172 after subtracting 1448 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Our division results in 232691.1988 with a remaining 0.00172.
