We divide 31111112 by 258
We want to divide 31111112 by 258.

Let's proceed to step 1:
258 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 258

On to step 2:
258 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 258

Going ahead to step 3:
If we divide 311 by 258, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 258 from 311 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 258

Going ahead to step 4:
When dividing 531 by 258, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 516 from 531, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 258

Step 5:
If we divide 151 by 258, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
The remainder is 151 after subtracting 0 from 151.
Bring next digit (1) of the dividend behind the 151 and repeat the process: 1511 / 258

Moving on to step 6:
If we divide 1511 by 258, we get 5 and a remainder of 221.
The next digit of our result is 5. 
Result so far: 1205.0
If we take 1290 away from 1511, we end up with 221.
Fetch the next digit (1) from the dividend, attach it to 221 and continue: 2211 / 258

Advancing to step 7:
2211 divided by 258 is 8 with a remainder of 147.
Record the quotient 8 as the next digit in the result. 
Result so far: 12058.0
The remainder is 147 after subtracting 2064 from 2211.
Fetch the next digit (2) from the dividend, attach it to 147 and continue: 1472 / 258

On to step 8:
When dividing 1472 by 258, we get 5 with a remainder of 182.
Use 5 as the next digit of our solution. 
Result so far: 120585.0
Subtract 1290 from 1472 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 9:
The number 258 fits into 1820 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 120585.7
If we subtract 1806 from 1820, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 258 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 120585.7
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 258 fits into 1400 5 times, leaving a remainder of 110.
The next digit of our result is 5. 
Result so far: 120585.705
Subtract 1290 from 1400 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
If we divide 1100 by 258, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 120585.7054
Deduct 1032 from 1100 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.

Going ahead to step 13:
When dividing 680 by 258, we get 2 with a remainder of 164.
The next digit of our result is 2. 
Result so far: 120585.70542
If we subtract 516 from 680, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 14:
The number 258 fits into 1640 6 times, leaving a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 120585.705426
Deduct 1548 from 1640 and we're left 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.

Going ahead to step 15:
258 goes into 920 3 times with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 120585.7054263
If we subtract 774 from 920, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 16:
258 can be fit into 1460 5 times, resulting in a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 120585.70542635
If we subtract 1290 from 1460, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 120585.70542635 with a balance of 1.7e-07.
