86148143 ÷ 336 
We're looking to find how many times 336 goes into 86148143.

Let's proceed to step 1:
When dividing 8 by 336, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 336

On to step 2:
If we divide 86 by 336, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 336

Advancing to step 3:
The number 336 fits into 861 2 times, leaving a remainder of 189.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 672 away from 861, we end up with 189.
Grab the next digit (4) from the dividend, add it to 189, then carry on: 1894 / 336

Advancing to step 4:
The number 336 fits into 1894 5 times, leaving a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 1680 away from 1894, we end up with 214.
Take the next digit (8) from the dividend and append it to 214, then repeat: 2148 / 336

Advancing to step 5:
If we divide 2148 by 336, we get 6 and a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
If we take 2016 away from 2148, we end up with 132.
Include the next digit (1) from the dividend after 132, then repeat: 1321 / 336

Advancing to step 6:
336 can be fit into 1321 3 times, resulting in a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 2563.0
If we take 1008 away from 1321, we end up with 313.
Grab the next digit (4) from the dividend, add it to 313, then carry on: 3134 / 336

Going ahead to step 7:
The number 336 fits into 3134 9 times, leaving a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 25639.0
Deduct 3024 from 3134 and we're left with 110.
Fetch the next digit (3) from the dividend, attach it to 110 and continue: 1103 / 336

Let's proceed to step 8:
When dividing 1103 by 336, we get 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 256393.0
Deduct 1008 from 1103 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
336 can be fit into 950 2 times, resulting in a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 256393.2
Deduct 672 from 950 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 10:
336 goes into 2780 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 256393.28
Subtracting 2688 from 2780 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 11:
920 divided by 336 is 2 with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 256393.282
If we take 672 away from 920, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 12:
When dividing 2480 by 336, we get 7 with a remainder of 128.
Record the quotient 7 as the next digit in the result. 
Result so far: 256393.2827
Subtract 2352 from 2480 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
336 can be fit into 1280 3 times, resulting in a remainder of 272.
Put 3 as the next digit of the answer. 
Result so far: 256393.28273
If we subtract 1008 from 1280, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
336 can be fit into 2720 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 256393.282738
Deduct 2688 from 2720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 15:
336 goes into 320 0 times with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 256393.282738
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
3200 divided by 336 is 9 with a remainder of 176.
Put 9 as the next digit of the answer. 
Result so far: 256393.28273809
If we subtract 3024 from 3200, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 256393.28273809 and a remainder of 1.76e-07.
