31451797 ÷ 220 
We want to figure out the number of times 31451797 can be divided by 220.

Going ahead to step 1:
220 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 220

Step 2:
When dividing 31 by 220, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 220

Moving on to step 3:
220 can be fit into 314 1 times, resulting in a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 220 from 314 and we're left with 94.
Include the next digit (5) from the dividend after 94, then repeat: 945 / 220

Step 4:
220 goes into 945 4 times with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 880 away from 945, we end up with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 220

Advancing to step 5:
When dividing 651 by 220, we get 2 with a remainder of 211.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we take 440 away from 651, we end up with 211.
Bring next digit (7) of the dividend behind the 211 and repeat the process: 2117 / 220

Step 6:
When dividing 2117 by 220, we get 9 with a remainder of 137.
The next digit of our result is 9. 
Result so far: 1429.0
If we take 1980 away from 2117, we end up with 137.
Grab the next digit (9) from the dividend, add it to 137, then carry on: 1379 / 220

Going ahead to step 7:
If we divide 1379 by 220, we get 6 and a remainder of 59.
Use 6 as the next digit of our solution. 
Result so far: 14296.0
Subtract 1320 from 1379 to get 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 220

Moving on to step 8:
220 goes into 597 2 times with a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 142962.0
If we subtract 440 from 597, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
220 goes into 1570 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 142962.7
Deduct 1540 from 1570 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 220, we get 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 142962.71
Subtracting 220 from 300 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
If we divide 800 by 220, we get 3 and a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 142962.713
Deduct 660 from 800 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
When dividing 1400 by 220, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 142962.7136
If we subtract 1320 from 1400, 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.

Going ahead to step 13:
If we divide 800 by 220, we get 3 and a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 142962.71363
The remainder is 140 after subtracting 660 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
The number 220 fits into 1400 6 times, leaving a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 142962.713636
If we take 1320 away from 1400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
220 goes into 800 3 times with a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 142962.7136363
The remainder is 140 after subtracting 660 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
220 can be fit into 1400 6 times, resulting in a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 142962.71363636
Deduct 1320 from 1400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 142962.71363636 with a remaining 8e-08.
