86921465 ÷ 370 
Our goal is to divide 86921465 by 370.

Step 1:
When dividing 8 by 370, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 370

Going ahead to step 2:
The number 370 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 370

Let's proceed to step 3:
869 divided by 370 is 2 with a remainder of 129.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 740 from 869 to get 129.
Take the next digit (2) from the dividend and append it to 129, then repeat: 1292 / 370

Moving on to step 4:
370 goes into 1292 3 times with a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1110 from 1292 to get 182.
Include the next digit (1) from the dividend after 182, then repeat: 1821 / 370

Advancing to step 5:
370 can be fit into 1821 4 times, resulting in a remainder of 341.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we subtract 1480 from 1821, we get 341.
Fetch the next digit (4) from the dividend, attach it to 341 and continue: 3414 / 370

Let's proceed to step 6:
When dividing 3414 by 370, we get 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 2349.0
The remainder is 84 after subtracting 3330 from 3414.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 370

Going ahead to step 7:
846 divided by 370 is 2 with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 23492.0
If we subtract 740 from 846, we get 106.
Fetch the next digit (5) from the dividend, attach it to 106 and continue: 1065 / 370

On to step 8:
When dividing 1065 by 370, we get 2 with a remainder of 325.
Put 2 as the next digit of the answer. 
Result so far: 234922.0
If we take 740 away from 1065, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 9:
If we divide 3250 by 370, we get 8 and a remainder of 290.
The number 8 becomes the next digit in our result. 
Result so far: 234922.8
Subtracting 2960 from 3250 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
370 goes into 2900 7 times with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 234922.87
If we take 2590 away from 2900, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 11:
The number 370 fits into 3100 8 times, leaving a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 234922.878
The remainder is 140 after subtracting 2960 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
When dividing 1400 by 370, we get 3 with a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 234922.8783
The remainder is 290 after subtracting 1110 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 13:
If we divide 2900 by 370, we get 7 and a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 234922.87837
The remainder is 310 after subtracting 2590 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 14:
3100 divided by 370 is 8 with a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 234922.878378
Subtract 2960 from 3100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
The number 370 fits into 1400 3 times, leaving a remainder of 290.
The next digit of our result is 3. 
Result so far: 234922.8783783
Deduct 1110 from 1400 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 16:
When dividing 2900 by 370, we get 7 with a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 234922.87837837
Subtracting 2590 from 2900 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 234922.87837837, with a leftover of 3.1e-07.
