We're dividing 37967890 by 991 
We're looking to find how many times 991 goes into 37967890.

Moving on to step 1:
The number 991 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 991

Advancing to step 2:
37 divided by 991 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 991

On to step 3:
The number 991 fits into 379 0 times, leaving a remainder of 379.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 379 to get 379.
Append the next digit (6) from the dividend to 379 and continue with: 3796 / 991

Going ahead to step 4:
When dividing 3796 by 991, we get 3 with a remainder of 823.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2973 from 3796, we get 823.
Take the next digit (7) from the dividend and append it to 823, then repeat: 8237 / 991

Moving on to step 5:
The number 991 fits into 8237 8 times, leaving a remainder of 309.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 7928 from 8237 and we're left with 309.
Bring next digit (8) of the dividend behind the 309 and repeat the process: 3098 / 991

Step 6:
3098 divided by 991 is 3 with a remainder of 125.
Write down 3 as next digit of the result. 
Result so far: 383.0
Subtract 2973 from 3098 to get 125.
Include the next digit (9) from the dividend after 125, then repeat: 1259 / 991

Let's proceed to step 7:
991 goes into 1259 1 times with a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 3831.0
If we subtract 991 from 1259, we get 268.
Append the next digit (0) from the dividend to 268 and continue with: 2680 / 991

Going ahead to step 8:
2680 divided by 991 is 2 with a remainder of 698.
Record the quotient 2 as the next digit in the result. 
Result so far: 38312.0
Subtracting 1982 from 2680 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 9:
991 can be fit into 6980 7 times, resulting in a remainder of 43.
The next digit of our result is 7. 
Result so far: 38312.7
The remainder is 43 after subtracting 6937 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
If we divide 430 by 991, we get 0 and a remainder of 430.
The next digit of our result is 0. 
Result so far: 38312.7
If we take 0 away from 430, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 11:
If we divide 4300 by 991, we get 4 and a remainder of 336.
Write down 4 as next digit of the result. 
Result so far: 38312.704
The remainder is 336 after subtracting 3964 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 12:
When dividing 3360 by 991, we get 3 with a remainder of 387.
Record the quotient 3 as the next digit in the result. 
Result so far: 38312.7043
If we take 2973 away from 3360, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 13:
The number 991 fits into 3870 3 times, leaving a remainder of 897.
Write down 3 as next digit of the result. 
Result so far: 38312.70433
Subtract 2973 from 3870 to get 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8970, and continue the process.

The final outcome is 38312.70433, with a leftover of 0.000897.
