42968191 ÷ 86 
We're looking to find how many times 86 goes into 42968191.

Moving on to step 1:
86 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
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 86

Advancing to step 2:
The number 86 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 86

Let's proceed to step 3:
When dividing 429 by 86, we get 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 344 from 429 leaves us with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 86

Moving on to step 4:
The number 86 fits into 856 9 times, leaving a remainder of 82.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 774 from 856 to get 82.
Grab the next digit (8) from the dividend, add it to 82, then carry on: 828 / 86

Going ahead to step 5:
The number 86 fits into 828 9 times, leaving a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 499.0
If we subtract 774 from 828, we get 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 86

Going ahead to step 6:
86 can be fit into 541 6 times, resulting in a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 4996.0
Subtracting 516 from 541 leaves us with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 86

Moving on to step 7:
86 goes into 259 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 49963.0
The remainder is 1 after subtracting 258 from 259.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 86

Step 8:
If we divide 11 by 86, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 499630.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
86 goes into 110 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 499630.1
Subtract 86 from 110 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
86 can be fit into 240 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 499630.12
Deduct 172 from 240 and we're left 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.

Advancing to step 11:
86 goes into 680 7 times with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 499630.127
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
86 goes into 780 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 499630.1279
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
When dividing 60 by 86, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 499630.1279
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 499630.127906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 15:
If we divide 840 by 86, we get 9 and a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 499630.1279069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 16:
660 divided by 86 is 7 with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 499630.12790697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 499630.12790697 with a remaining 5.8e-08.
