31091098 ÷ 616 
We're looking to find how many times 616 goes into 31091098.

Step 1:
The number 616 fits into 3 0 times, leaving 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.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 616

Moving on to step 2:
31 divided by 616 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 616

Step 3:
When dividing 310 by 616, we get 0 with a remainder of 310.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 310 to get 310.
Fetch the next digit (9) from the dividend, attach it to 310 and continue: 3109 / 616

Step 4:
The number 616 fits into 3109 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3080 from 3109, we get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 616

Moving on to step 5:
If we divide 291 by 616, we get 0 and a remainder of 291.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 291 to get 291.
Include the next digit (0) from the dividend after 291, then repeat: 2910 / 616

Moving on to step 6:
When dividing 2910 by 616, we get 4 with a remainder of 446.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
Subtracting 2464 from 2910 leaves us with 446.
Grab the next digit (9) from the dividend, add it to 446, then carry on: 4469 / 616

Step 7:
616 goes into 4469 7 times with a remainder of 157.
Put 7 as the next digit of the answer. 
Result so far: 5047.0
The remainder is 157 after subtracting 4312 from 4469.
Take the next digit (8) from the dividend and append it to 157, then repeat: 1578 / 616

Moving on to step 8:
1578 divided by 616 is 2 with a remainder of 346.
Record the quotient 2 as the next digit in the result. 
Result so far: 50472.0
Subtracting 1232 from 1578 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 9:
3460 divided by 616 is 5 with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 50472.5
If we take 3080 away from 3460, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
If we divide 3800 by 616, we get 6 and a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 50472.56
Subtracting 3696 from 3800 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
616 can be fit into 1040 1 times, resulting in a remainder of 424.
The next digit of our result is 1. 
Result so far: 50472.561
Subtracting 616 from 1040 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 12:
4240 divided by 616 is 6 with a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 50472.5616
If we take 3696 away from 4240, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 13:
The number 616 fits into 5440 8 times, leaving a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 50472.56168
The remainder is 512 after subtracting 4928 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 14:
If we divide 5120 by 616, we get 8 and a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 50472.561688
If we subtract 4928 from 5120, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 50472.561688, with a leftover of 1.92e-05.
