42179898 divided by 154 
We want to divide 42179898 by 154.

Advancing to step 1:
When dividing 4 by 154, we get 0 with 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.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 154

Moving on to step 2:
The number 154 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 154

Step 3:
154 goes into 421 2 times with a remainder of 113.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 113 after subtracting 308 from 421.
Grab the next digit (7) from the dividend, add it to 113, then carry on: 1137 / 154

On to step 4:
The number 154 fits into 1137 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 1078 from 1137 and we're left with 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 154

Step 5:
154 can be fit into 599 3 times, resulting in a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 273.0
If we subtract 462 from 599, we get 137.
Take the next digit (8) from the dividend and append it to 137, then repeat: 1378 / 154

On to step 6:
The number 154 fits into 1378 8 times, leaving a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 2738.0
The remainder is 146 after subtracting 1232 from 1378.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 154

Step 7:
1469 divided by 154 is 9 with a remainder of 83.
Use 9 as the next digit of our solution. 
Result so far: 27389.0
Deduct 1386 from 1469 and we're left with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 154

Advancing to step 8:
154 can be fit into 838 5 times, resulting in a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 273895.0
Subtracting 770 from 838 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
The number 154 fits into 680 4 times, leaving a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 273895.4
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
154 can be fit into 640 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 273895.44
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 273895.44 and a remainder of 0.024.
