We look at the division of 80137312 by 349 
We want to figure out the number of times 80137312 can be divided by 349.

Step 1:
When dividing 8 by 349, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 349

Advancing to step 2:
The number 349 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 349

On to step 3:
349 can be fit into 801 2 times, resulting in a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 698 away from 801, we end up with 103.
Include the next digit (3) from the dividend after 103, then repeat: 1033 / 349

Step 4:
If we divide 1033 by 349, we get 2 and a remainder of 335.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 698 from 1033 leaves us with 335.
Grab the next digit (7) from the dividend, add it to 335, then carry on: 3357 / 349

Advancing to step 5:
If we divide 3357 by 349, we get 9 and a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 229.0
Deduct 3141 from 3357 and we're left with 216.
Include the next digit (3) from the dividend after 216, then repeat: 2163 / 349

Going ahead to step 6:
When dividing 2163 by 349, we get 6 with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 2296.0
If we take 2094 away from 2163, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 349

On to step 7:
349 goes into 691 1 times with a remainder of 342.
The next digit of our result is 1. 
Result so far: 22961.0
Subtract 349 from 691 to get 342.
Fetch the next digit (2) from the dividend, attach it to 342 and continue: 3422 / 349

Let's proceed to step 8:
The number 349 fits into 3422 9 times, leaving a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 229619.0
If we take 3141 away from 3422, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
2810 divided by 349 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 229619.8
Subtracting 2792 from 2810 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
349 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 229619.8
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
When dividing 1800 by 349, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 229619.805
Deduct 1745 from 1800 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
If we divide 550 by 349, we get 1 and a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 229619.8051
If we take 349 away from 550, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 13:
The number 349 fits into 2010 5 times, leaving a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 229619.80515
Deduct 1745 from 2010 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 14:
If we divide 2650 by 349, we get 7 and a remainder of 207.
Write down 7 as next digit of the result. 
Result so far: 229619.805157
If we subtract 2443 from 2650, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 15:
The number 349 fits into 2070 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 229619.8051575
If we subtract 1745 from 2070, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 16:
When dividing 3250 by 349, we get 9 with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 229619.80515759
Subtract 3141 from 3250 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

After the division, we end up with 229619.80515759 and a remainder of 1.09e-07.
