31138070 divided by 345 
Let's see how many times 345 fits into 31138070.

Let's proceed to step 1:
345 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
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 / 345

Step 2:
If we divide 31 by 345, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 345

Going ahead to step 3:
If we divide 311 by 345, we get 0 and a remainder of 311.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Grab the next digit (3) from the dividend, add it to 311, then carry on: 3113 / 345

Moving on to step 4:
If we divide 3113 by 345, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 3105 from 3113, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 345

Step 5:
345 can be fit into 88 0 times, resulting in a remainder of 88.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 88 to get 88.
Bring next digit (0) of the dividend behind the 88 and repeat the process: 880 / 345

Advancing to step 6:
345 can be fit into 880 2 times, resulting in a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 902.0
The remainder is 190 after subtracting 690 from 880.
Bring next digit (7) of the dividend behind the 190 and repeat the process: 1907 / 345

Advancing to step 7:
345 can be fit into 1907 5 times, resulting in a remainder of 182.
Put 5 as the next digit of the answer. 
Result so far: 9025.0
Subtract 1725 from 1907 to get 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 345

On to step 8:
When dividing 1820 by 345, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 90255.0
If we subtract 1725 from 1820, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
950 divided by 345 is 2 with a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 90255.2
If we subtract 690 from 950, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
345 goes into 2600 7 times with a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 90255.27
Subtracting 2415 from 2600 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 11:
If we divide 1850 by 345, we get 5 and a remainder of 125.
The next digit of our result is 5. 
Result so far: 90255.275
Subtracting 1725 from 1850 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
345 goes into 1250 3 times with a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 90255.2753
If we take 1035 away from 1250, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 13:
345 can be fit into 2150 6 times, resulting in a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 90255.27536
If we subtract 2070 from 2150, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
When dividing 800 by 345, we get 2 with a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 90255.275362
Deduct 690 from 800 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 15:
When dividing 1100 by 345, we get 3 with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 90255.2753623
If we take 1035 away from 1100, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 16:
345 can be fit into 650 1 times, resulting in a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 90255.27536231
Subtracting 345 from 650 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 90255.27536231 and a remainder of 3.05e-07.
