We divide 31591998 by 37
Let's see how many times 37 fits into 31591998.

Step 1:
The number 37 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 37

Advancing to step 2:
The number 37 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 37

Going ahead to step 3:
315 divided by 37 is 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 296 from 315 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 37

Going ahead to step 4:
The number 37 fits into 199 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 185 from 199, we get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 37

Going ahead to step 5:
When dividing 141 by 37, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 853.0
If we subtract 111 from 141, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 37

Step 6:
37 goes into 309 8 times with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 8538.0
Deduct 296 from 309 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 37

Going ahead to step 7:
37 can be fit into 139 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 85383.0
Deduct 111 from 139 and we're left with 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 37

Moving on to step 8:
37 goes into 288 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 853837.0
Subtract 259 from 288 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
37 goes into 290 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 853837.7
Subtract 259 from 290 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
37 can be fit into 310 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 853837.78
Subtract 296 from 310 to 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.

Step 11:
When dividing 140 by 37, we get 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 853837.783
The remainder is 29 after subtracting 111 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
When dividing 290 by 37, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 853837.7837
Subtracting 259 from 290 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
310 divided by 37 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 853837.78378
Deduct 296 from 310 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
When dividing 140 by 37, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 853837.783783
Subtracting 111 from 140 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 15:
37 goes into 290 7 times with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 853837.7837837
Subtracting 259 from 290 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 16:
If we divide 310 by 37, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 853837.78378378
If we subtract 296 from 310, 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.

The final outcome is 853837.78378378, with a leftover of 1.4e-08.
