Let's divide 31121992 by 557
We want to divide 31121992 by 557.

On to step 1:
The number 557 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 557

Moving on to step 2:
When dividing 31 by 557, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the 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 / 557

Moving on to step 3:
If we divide 311 by 557, we get 0 and a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Fetch the next digit (2) from the dividend, attach it to 311 and continue: 3112 / 557

Step 4:
557 goes into 3112 5 times with a remainder of 327.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 327 after subtracting 2785 from 3112.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 557

Advancing to step 5:
557 can be fit into 3271 5 times, resulting in a remainder of 486.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 2785 away from 3271, we end up with 486.
Bring next digit (9) of the dividend behind the 486 and repeat the process: 4869 / 557

Step 6:
If we divide 4869 by 557, we get 8 and a remainder of 413.
Put 8 as the next digit of the answer. 
Result so far: 558.0
Subtracting 4456 from 4869 leaves us with 413.
Bring next digit (9) of the dividend behind the 413 and repeat the process: 4139 / 557

Moving on to step 7:
If we divide 4139 by 557, we get 7 and a remainder of 240.
The number 7 becomes the next digit in our result. 
Result so far: 5587.0
The remainder is 240 after subtracting 3899 from 4139.
Append the next digit (2) from the dividend to 240 and continue with: 2402 / 557

On to step 8:
The number 557 fits into 2402 4 times, leaving a remainder of 174.
The next digit of our result is 4. 
Result so far: 55874.0
The remainder is 174 after subtracting 2228 from 2402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
If we divide 1740 by 557, we get 3 and a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 55874.3
Subtracting 1671 from 1740 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
557 goes into 690 1 times with a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 55874.31
If we subtract 557 from 690, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 11:
If we divide 1330 by 557, we get 2 and a remainder of 216.
The next digit of our result is 2. 
Result so far: 55874.312
The remainder is 216 after subtracting 1114 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 12:
If we divide 2160 by 557, we get 3 and a remainder of 489.
Put 3 as the next digit of the answer. 
Result so far: 55874.3123
Deduct 1671 from 2160 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Let's proceed to step 13:
557 goes into 4890 8 times with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 55874.31238
If we subtract 4456 from 4890, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 14:
557 can be fit into 4340 7 times, resulting in a remainder of 441.
Put 7 as the next digit of the answer. 
Result so far: 55874.312387
If we take 3899 away from 4340, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 15:
557 goes into 4410 7 times with a remainder of 511.
The next digit of our result is 7. 
Result so far: 55874.3123877
Subtract 3899 from 4410 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

In conclusion, the division gives 55874.3123877 with a balance of 5.11e-06.
