42126392 ÷ 170 
We want to divide 42126392 by 170.

Advancing to step 1:
The number 170 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 170

Going ahead to step 2:
If we divide 42 by 170, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 170

On to step 3:
When dividing 421 by 170, we get 2 with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 340 from 421 to get 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 170

Let's proceed to step 4:
170 can be fit into 812 4 times, resulting in a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 680 from 812 to get 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 170

Advancing to step 5:
When dividing 1326 by 170, we get 7 with a remainder of 136.
The next digit of our result is 7. 
Result so far: 247.0
The remainder is 136 after subtracting 1190 from 1326.
Bring next digit (3) of the dividend behind the 136 and repeat the process: 1363 / 170

Let's proceed to step 6:
The number 170 fits into 1363 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 2478.0
If we subtract 1360 from 1363, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 170

On to step 7:
When dividing 39 by 170, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 24780.0
If we subtract 0 from 39, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 170

Going ahead to step 8:
The number 170 fits into 392 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 247802.0
If we subtract 340 from 392, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
The number 170 fits into 520 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 247802.3
Subtracting 510 from 520 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 170 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 247802.3
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
If we divide 1000 by 170, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 247802.305
Deduct 850 from 1000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
170 goes into 1500 8 times with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 247802.3058
If we subtract 1360 from 1500, we 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 13:
1400 divided by 170 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 247802.30588
If we take 1360 away from 1400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 247802.30588 with a remaining 4e-05.
