31721638 divided by 148 
We're looking to find how many times 148 goes into 31721638.

Let's proceed to step 1:
If we divide 3 by 148, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 148

Advancing to step 2:
148 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 148

Let's proceed to step 3:
148 goes into 317 2 times with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 296 from 317 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 148

Step 4:
212 divided by 148 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 148 from 212 leaves us with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 148

Moving on to step 5:
148 goes into 641 4 times with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 214.0
Subtract 592 from 641 to get 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 148

Advancing to step 6:
496 divided by 148 is 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 2143.0
The remainder is 52 after subtracting 444 from 496.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 148

Going ahead to step 7:
When dividing 523 by 148, we get 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 21433.0
If we subtract 444 from 523, we get 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 148

Going ahead to step 8:
When dividing 798 by 148, we get 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 214335.0
Deduct 740 from 798 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
580 divided by 148 is 3 with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 214335.3
Subtract 444 from 580 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
1360 divided by 148 is 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 214335.39
If we subtract 1332 from 1360, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
280 divided by 148 is 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 214335.391
Subtract 148 from 280 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
The number 148 fits into 1320 8 times, leaving a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 214335.3918
If we take 1184 away from 1320, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
If we divide 1360 by 148, we get 9 and a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 214335.39189
If we subtract 1332 from 1360, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
148 goes into 280 1 times with a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 214335.391891
If we subtract 148 from 280, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 15:
If we divide 1320 by 148, we get 8 and a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 214335.3918918
If we take 1184 away from 1320, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 16:
1360 divided by 148 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 214335.39189189
If we take 1332 away from 1360, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 214335.39189189 with a remainder of 2.8e-08.
