We divide 13397523 by 231
We want to divide 13397523 by 231.

Moving on to step 1:
When dividing 1 by 231, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 231

Advancing to step 2:
If we divide 13 by 231, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 231

Let's proceed to step 3:
231 can be fit into 133 0 times, resulting in a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 133 after subtracting 0 from 133.
Bring next digit (9) of the dividend behind the 133 and repeat the process: 1339 / 231

Advancing to step 4:
231 can be fit into 1339 5 times, resulting in a remainder of 184.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 1155 from 1339 and we're left with 184.
Bring next digit (7) of the dividend behind the 184 and repeat the process: 1847 / 231

Moving on to step 5:
1847 divided by 231 is 7 with a remainder of 230.
The next digit of our result is 7. 
Result so far: 57.0
If we take 1617 away from 1847, we end up with 230.
Grab the next digit (5) from the dividend, add it to 230, then carry on: 2305 / 231

On to step 6:
2305 divided by 231 is 9 with a remainder of 226.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
The remainder is 226 after subtracting 2079 from 2305.
Fetch the next digit (2) from the dividend, attach it to 226 and continue: 2262 / 231

Moving on to step 7:
When dividing 2262 by 231, we get 9 with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 5799.0
Deduct 2079 from 2262 and we're left with 183.
Fetch the next digit (3) from the dividend, attach it to 183 and continue: 1833 / 231

On to step 8:
When dividing 1833 by 231, we get 7 with a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 57997.0
Subtracting 1617 from 1833 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
If we divide 2160 by 231, we get 9 and a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 57997.9
If we subtract 2079 from 2160, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
231 can be fit into 810 3 times, resulting in a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 57997.93
Subtract 693 from 810 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 11:
The number 231 fits into 1170 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 57997.935
If we take 1155 away from 1170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
If we divide 150 by 231, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 57997.935
Deduct 0 from 150 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.

Advancing to step 13:
The number 231 fits into 1500 6 times, leaving a remainder of 114.
Record the quotient 6 as the next digit in the result. 
Result so far: 57997.93506
Deduct 1386 from 1500 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 14:
1140 divided by 231 is 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 57997.935064
If we take 924 away from 1140, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 15:
The number 231 fits into 2160 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 57997.9350649
If we take 2079 away from 2160, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 16:
If we divide 810 by 231, we get 3 and a remainder of 117.
Write down 3 as next digit of the result. 
Result so far: 57997.93506493
Deduct 693 from 810 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final outcome is 57997.93506493, with a leftover of 1.17e-07.
