Let's divide 86991959 by 337
We're looking to find how many times 337 goes into 86991959.

On to step 1:
8 divided by 337 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 337

Let's proceed to step 2:
86 divided by 337 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 337

Step 3:
869 divided by 337 is 2 with a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 674 from 869 leaves us with 195.
Include the next digit (9) from the dividend after 195, then repeat: 1959 / 337

Moving on to step 4:
When dividing 1959 by 337, we get 5 with a remainder of 274.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 1685 from 1959 to get 274.
Grab the next digit (1) from the dividend, add it to 274, then carry on: 2741 / 337

Advancing to step 5:
337 goes into 2741 8 times with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
Deduct 2696 from 2741 and we're left with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 337

Moving on to step 6:
337 can be fit into 459 1 times, resulting in a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 2581.0
Deduct 337 from 459 and we're left with 122.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 337

Step 7:
337 can be fit into 1225 3 times, resulting in a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 25813.0
Deduct 1011 from 1225 and we're left with 214.
Bring next digit (9) of the dividend behind the 214 and repeat the process: 2149 / 337

Moving on to step 8:
2149 divided by 337 is 6 with a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 258136.0
Subtract 2022 from 2149 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
337 can be fit into 1270 3 times, resulting in a remainder of 259.
Record the quotient 3 as the next digit in the result. 
Result so far: 258136.3
Subtracting 1011 from 1270 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 10:
337 goes into 2590 7 times with a remainder of 231.
Record the quotient 7 as the next digit in the result. 
Result so far: 258136.37
Subtracting 2359 from 2590 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 11:
337 can be fit into 2310 6 times, resulting in a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 258136.376
Deduct 2022 from 2310 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
The number 337 fits into 2880 8 times, leaving a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 258136.3768
If we take 2696 away from 2880, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 13:
337 can be fit into 1840 5 times, resulting in a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 258136.37685
If we take 1685 away from 1840, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 14:
337 goes into 1550 4 times with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 258136.376854
Subtracting 1348 from 1550 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 15:
337 can be fit into 2020 5 times, resulting in a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 258136.3768545
Subtract 1685 from 2020 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 16:
337 can be fit into 3350 9 times, resulting in a remainder of 317.
Use 9 as the next digit of our solution. 
Result so far: 258136.37685459
Deduct 3033 from 3350 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

After the division, we end up with 258136.37685459 and a remainder of 3.17e-07.
