We're dividing 87137571 by 401 
Our goal is to divide 87137571 by 401.

Advancing to step 1:
8 divided by 401 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 401

Going ahead to step 2:
401 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 401

Let's proceed to step 3:
If we divide 871 by 401, we get 2 and a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 802 from 871 and we're left with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 401

On to step 4:
693 divided by 401 is 1 with a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 401 from 693 and we're left with 292.
Append the next digit (7) from the dividend to 292 and continue with: 2927 / 401

Moving on to step 5:
401 goes into 2927 7 times with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 2807 from 2927 and we're left with 120.
Include the next digit (5) from the dividend after 120, then repeat: 1205 / 401

On to step 6:
1205 divided by 401 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 2173.0
Deduct 1203 from 1205 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 401

Going ahead to step 7:
The number 401 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 21730.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 401

Going ahead to step 8:
The number 401 fits into 271 0 times, leaving a remainder of 271.
The number 0 becomes the next digit in our result. 
Result so far: 217300.0
If we subtract 0 from 271, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 9:
401 goes into 2710 6 times with a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 217300.6
The remainder is 304 after subtracting 2406 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 10:
401 goes into 3040 7 times with a remainder of 233.
Record the quotient 7 as the next digit in the result. 
Result so far: 217300.67
Deduct 2807 from 3040 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 11:
2330 divided by 401 is 5 with a remainder of 325.
The next digit of our result is 5. 
Result so far: 217300.675
If we subtract 2005 from 2330, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 12:
The number 401 fits into 3250 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 217300.6758
The remainder is 42 after subtracting 3208 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
401 goes into 420 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 217300.67581
Subtracting 401 from 420 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
The number 401 fits into 190 0 times, leaving a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 217300.67581
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
The number 401 fits into 1900 4 times, leaving a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 217300.6758104
Subtract 1604 from 1900 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
401 goes into 2960 7 times with a remainder of 153.
Record the quotient 7 as the next digit in the result. 
Result so far: 217300.67581047
Deduct 2807 from 2960 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

In conclusion, the division gives 217300.67581047 with a balance of 1.53e-07.
