52640070 divided by 397 
We want to divide 52640070 by 397.

On to step 1:
If we divide 5 by 397, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 397

Moving on to step 2:
The number 397 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 397

Step 3:
526 divided by 397 is 1 with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 129 after subtracting 397 from 526.
Bring next digit (4) of the dividend behind the 129 and repeat the process: 1294 / 397

Going ahead to step 4:
When dividing 1294 by 397, we get 3 with a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 103 after subtracting 1191 from 1294.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 397

Going ahead to step 5:
397 goes into 1030 2 times with a remainder of 236.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtracting 794 from 1030 leaves us with 236.
Take the next digit (0) from the dividend and append it to 236, then repeat: 2360 / 397

Going ahead to step 6:
397 can be fit into 2360 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 1325.0
The remainder is 375 after subtracting 1985 from 2360.
Fetch the next digit (7) from the dividend, attach it to 375 and continue: 3757 / 397

Step 7:
When dividing 3757 by 397, we get 9 with a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 13259.0
Subtracting 3573 from 3757 leaves us with 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 397

Going ahead to step 8:
397 goes into 1840 4 times with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 132594.0
If we subtract 1588 from 1840, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 9:
397 goes into 2520 6 times with a remainder of 138.
The next digit of our result is 6. 
Result so far: 132594.6
Deduct 2382 from 2520 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 10:
397 goes into 1380 3 times with a remainder of 189.
Use 3 as the next digit of our solution. 
Result so far: 132594.63
The remainder is 189 after subtracting 1191 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 11:
1890 divided by 397 is 4 with a remainder of 302.
The number 4 becomes the next digit in our result. 
Result so far: 132594.634
If we take 1588 away from 1890, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 12:
If we divide 3020 by 397, we get 7 and a remainder of 241.
Record the quotient 7 as the next digit in the result. 
Result so far: 132594.6347
Deduct 2779 from 3020 and we're left with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 13:
The number 397 fits into 2410 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 132594.63476
If we take 2382 away from 2410, 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.

Let's proceed to step 14:
The number 397 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 132594.63476
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
397 can be fit into 2800 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 132594.6347607
Subtracting 2779 from 2800 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 16:
397 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 132594.6347607
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 132594.6347607, with a leftover of 2.1e-07.
